Update November 2021

We are tracking an issue with all or nearly all mobs in the area around the player vanishing when the world is reloaded in versions 1.17.30 through 1.18.2 Hotfix at MCPE-144208. Please do not comment here if that describes your experience.

Moderator Note by [~DrAwesome4333] and [~GoldenHelmet]

Please limit comments to New information about the issue. A short list of what is most helpful and what is not is listed below. Please take the time to read this brief list before commenting.

A list of mobs you have lost is not helpful information. We know this bug can impact any mob, we know that leashed mobs that despawn will leave behind a leash knot, and we know that when villagers despawn their beds and workstations remain linked to the missing villager until you break them or 20 minutes pass. What might be helpful are details about things like

what you were doing leading up to the mobs disappearing
single vs. multiplayer, local vs server/realm
how far you traveled
how long the current or previous play session lasted
whether the despawns were near a player spawn point or if you had changed your player spawn point during the session,
if you experienced lag or anything else abnormal.

Workaround (updated Dec. 5, 2020)

Some cases of persistent mobs despawning can be traced to them crossing chunk borders between saves, so one way to guard against randomly losing mobs is to prevent them from crossing chunk borders (you can read about finding chunk borders on the wiki). However, this is not a guarantee or a fix. Positioning mobs away from chunk borders does not mean you will never lose a persistent mob again. Many cases of mobs randomly despawning remain unexplained by the tracker staff and player community.

Updated description by @unknown July 22, 2020
This ticket is used as parent for all otherwise unexplained mob disappearances. It covers mobs disappearing related to nether portal travel, long distance single-dimension travel, crashes, realm lag, and any other circumstance, except for the specific circumstances covered by MCPE-88322, MCPE-66818, MCPE-51837, MCPE-16863, and MCPE-108568, MCPE-141539, and MCPE-144208.

Some random mob despawns can be explained by the mobs crossing chunk borders between auto-saves. Other random mob despawns are reported for mobs that were unable to cross chunk borders.

I have attached a test world that can be used to reproduce despawning on chunk borders due to a crash with the following steps to reproduce:

Load [^[EX] Chunk border despawn demo.mcworld].
Press the button to spawn a villager.
Save & quit, then reload, to confirm that the the villager is kept in the world save.
Open the world, flip the lever, and start a stopwatch.
After about 10-15 seconds, close Minecraft without exiting the world (for example, in Windows 10 press alt-F4).
Reopen Minecraft and reopen the test world.

Expected result

The villager is still present.

Actual result

Sometimes the villager will be gone. I estimate this occurs about once out of 20 attempts. You can see the entire sequence in

[media]

What happens when the villager disappears is that sometime between flipping the lever and force-closing the game, the chunk in which the player is located gets auto-saved and the chunk to the right does not. You can verify this by observing that a honey block is also missing--the fact it was pushed out of the left chunk by the piston is saved, but the fact it was pushed into the right chunk is not.

Original description
When I go to Nether and I went back my horses an my animal that I feed is disappear

Edit by @unknown: When playing on multiplayer, entities can despawn when you travel to the Nether and back to the Overworld.

Keep in mind that naturally-spawned monsters and animals that have never been interacted with are SUPPOSED to despawn. When testing this bug, please make sure to interact with monsters or animals you're observing first, by tempting them with food, breeding, or name-tagging them. This is not necessary for villagers or iron golems.

Same problem for me. I went to the nether on LAN with all the players on the world. When we returned after 10 minutes, all the mobs in the world had despawned.

I'm not sure where to put this, but this seems the best place as https://bugs.mojang.com/browse/MCPE-8002 is now closed as fixed.

On our realm, we continually have villagers and animals despawn. At first I was ecstatic after MCPE-8002 was resolved, but then it wasn't. So then it appeared that it had to do with going to/from the nether. I destroyed all nearby portals in the hopes that moving between nether and overworld had to do with chunks being loaded. I've got this great shiny barn/village center that I built, connected to a zombie spawner, set up conversion centers, conveyance systems.... and the ~30 villagers that I put there are all gone. Again. For the third time. It's one thing to lose hours of work because you do something dumb like fall in lava. It's another to lose many, many hours of work because of bugs. Never mind the utility lost (mostly collect librarians; we've now lost a few unbreak3's, silk touch, infinity, efficiency 4, etc) in this latest batch of despawns.

@unknown: Unfortunately, the bug has only been fixed for singleplayer. Realms and multiplayer still suffer from it.

migrated 2017-05-13T20:40:55Z

Any update on when this bug get fixed?
We pay for a MCPE realm and this keeps happening to us.
My kids and I keep losing farm and more importantly horses we spend hours to find and bring back to our farm.

Now every time we enter the Nether they will despawn. It really kills te experience and it breaks my heart to see my sons sad face every time he finds out his horses are gone.

Dr.Awesome4333 2017-05-14T03:36:42Z

@unknown, please do not ask when a bug will be fixed as the honest answer is we do not know. When this bug is fixed is up to the developers as some bugs may be very complex and difficult to fix and will take time.

I recently joined a realm and purposefully built 2000+ blocks away from spawn (and nether portal). I have had many animals repeatedly despawning or somehow missing from their pens including far away or hard to find animals like fast horses, donkeys and rabbits. I have interacted with them by either riding or leading them with carrot to get them to the penned area. There are individual animal pens for each kind of animal and also a large fence around the perimeter of my area so they would have to escape through both fences or I would see them in between. It is possible they are somehow suffocating in the fence and dying so I also commented on MCPE 1982. This bug does not seem to have to do with the nether for me as I cross an ocean in a boat to get to spawn and the nether. Also, my house is far away from any other players and I do not have visitors so it doesn't seem to have to do with the multiplayer aspect either. I thought the bug I have been experiencing is MCPE 8002, but since it was listed as resolved and this specific game I am playing is on a realm I'm also commenting here. I am playing on Windows 10 Edition version 1.0.8. Again, the animals I am losing are 2000+ blocks from spawn, nether hub and other players do not come here.

Just got this bug! On a friends multiplayer realm, with quite a few days of work with villagers, horses, golems, wolves etc. all secured in areas with leashes / gates and name tagged and as I returned from my travels and my friend returned from the nether, all of these things had subsequently despawned. I assume not, but I was hoping there would be some kind of temporary fix (such as reloading to a previous version). This occurred on the Windows 10 edition with only us in game.

Just happened to my realm. I was building in the Nether, and my SO joined me briefly to supply me with some building blocks, after feeding our chicken. When he returned, ALL our animals are gone. Tame horses, saddled and armored horses, pet wolves, chicken, sheep of all sort of colors, cows, pigs, donkeys... 100s of animals just POOF, leaving empty pens behind as if they were just raptured!

Help? This farm took a while to tend to this size... 😞

Tried to make a villager breeder on realms twice. Detector villager disappeared. Replaced with villager in minecart. It disappeared along with minecart AND the three breeder villagers above. So far, the six trader villagers, also in minecarts, haven't disappeared (mending trade, PLEASE don't disappear lol)

Anyway, not sure of the cause but my nether portal is at x 232 and the trader villagers are at x 95 with very similar z values.

migrated 2017-07-09T11:52:17Z

This is also happening on my single player survival world, both the chunk loading error (which sometimes resolves quickly and sometimes does not) and the disappearing villagers in my trading center. I had about 35 farmers all in separate mine carts in separate unpowered powered rails, and 10 of them disappeared after a trip to the Nether. Also all my seeder chickens in my chicken cooker despawn and my cows are despawning too. At first I thought it was due to entity cramming, but I popped some eggs and got 2 more in the seeder area, then fed them and bred them with seeds so there were only 3 and they eventually disappeared after a few trips to the nether or the end. Without the F3 debugging data, I can't tell if these farms are on chunk borders or not, but near the same line as my chicken breeder, I also had several rows of signs disappear in my iron golem farm and I had several item frames disappear off my storage system. I have since moved my storage system to a different location and switched the design of the iron farm, but the chicken issue still happens and the cow farm is in a different area.

MS Hosted Realm (3-player, $3.99/mo)
Android MCPE 1.1.3 (Amazon Fire Tab 7 / Samsung Galaxy Tab A)

1.) Created a new nether portal in the Realm by main homestead.
2.) Went through nether portal, returned within 60 seconds to overworld.
3.) All animals and paintings from inside the house were gone.

All of these animals had been interacted with in the past 24 hours or less as we had recently re-organized the entire homestead. All animals were kept in either 2-block deep pits surrounded by cobblestone fences with a single birch gate, or the horses were in a cobblestone fenced yard. We lost cows, chickens, sheep (natural & dyed), pigs, and horses (both armored & saddled).

We also lost all paintings from inside our house. This included multiple sizes and shapes.

We are still investigating to see what other items have been removed.

Wait is this a bug about entities despawning or chunk loading bug? I've had chunk loading on Windows 10 and mobs despawn in on the row on Windows 10

migrated 2017-07-21T00:57:22Z

This despawn zone is linked to either portal location (less likely) or world spawn.

We have a large world where the farms close to world spawn have had animals (and paintings, as mentioned) despawned several times. Most recently, a safety ark was created at chunk 12, -3 and these animals still despawned. There is another farm at chunk -30, -21 which was safe from the despawn.

The main portal is located fairly close to world spawn, so it's difficult to isolate where the despawn zone is centred, but I would imagine it is world spawn.

I guess your best bet for now is to have your farms at least 20 chunks away from world spawn until this gets fixed.

migrated 2017-08-17T01:43:49Z

I have experienced this bug any time on my realms server. It has happened both with mobs I have and have not interacted with. In the nether, the mobs still despawn. It has occurred with cows,sheep,horses, and donkeys. I have found these after I or another member went through a nether portal. All the farms have been near world spawn or in the nether (near nether portal from spawn).

migrated 2017-08-19T22:06:59Z

I had this happen to me also. Lost multiple tamed horses, and their saddles and armor. Also lost sheep and cows. It happened when I came out of a nether portal near spawn.

Same experiences here using Windows 10 edition. Animals clustering and both my (realm owner) and another player's domesticated animal mobs vanishing upon returning from a foray into the nether. Dogs, sheep, cows, horses, all recently interacted with. Nether portal near world spawn point.

Have just got the same issue.
Playing with my son, spent ages building pens and breeding sheep, cows, chickens, rabbits - capturing horses etc...
Had some pigs in pens as well - strangely it appeared these were unaffected?

Both of us went to nether only to return and find all animals that were in our pens were gone!
Windows 10 Edition v1.1.5 (Build 421475), using Realm - need to fix this ASAP - lost a ton of work getting all those animals built up.

Nether Portal is at least 150 blocks away from where animals were penned up.

migrated 2017-09-15T03:17:34Z

Can confirm the issue as it has happened multiple times upon returning from the nether. This is related to all entities and not just animals. Chicken and cow farms are now completely empty. All minecarts with hoppers have also disappeared.

W10 Edition on a Realm.

Not sure if the nether is involved specifically, but twice now I have logged in to find that my horse pen, having previously contained maybe seven or eight horses/donkeys/mules, is suddenly down to four. Despawned creatures include those which were wearing gear, and even some that I had nametagged. Ridiculous. I am certain that this has nothing to do with the direct intervention of other players or creatures.

edit: Two more gone from a pen of four, including the last nametagged one.

edit 10/18/17: I'm now largely convinced that the Nether really is at fault. After avoiding it for two weeks and not having any despawn problems, I set foot inside again today and came back to find one of my two horses missing, as in prior instances.

Windows 10 on minecraft pe bedrock edition playing with 4 people on realm and my villagers keep despawning. they despawn from minecarts and from a closed in enclosure, they despawn even if I have traded with them or if i've fed them. this keeps breaking my breeder and I wont be able to make an iron farm. I even tried to put them in a ticking area but that doesn't matter. they despawn when I log out and my redstone circuits unsync and have to be reset. I have a dispenser hooked up to a hopper with chickens on top and when the dispenser has an inventory there is a circuit that pulses a redstone signal on the dispenser and a very complicated circuit to pick up lava and wait for the baby chickens to fall back down because the dispenser firing into a half slab still hits the baby chicks with eggs(another bug) but when i go and check on it after a couple of days it de-syncs and is now placing down lava instead of picking it back up. it happens when I go to the nether or log out sometimes.

Mega_Spud asked me to include my observations from a duplicate report I added, so I just copypasta'd the whole thing, as I don't have time right now to boil it down:

I'm playing in a realm, and I had just checked on all my animals last night, as I'd been gone from the game for a few days, and had been at another location a about 2000 blocks away for a few days before that. Everything was fine last night.

I took a long trip to my friends' place (10,000 blocks or more away, where they have refurbished a Woodland Mansion) and returned late last night. Today, when I return to the realm, EVERYTHING it seems has had some degree of despawning for no reason: horses, sheep, pigs, chickens and even a few doors. The animals are all in pens and have been fed and raised by me, the horses were saddled and my favorite had been ridden often, named twice (the nametag keeps disappearing, too, which is a separate issue), saddled and armored.

I had several different sheep of each of the four natural colors and now have a few browns, a white and a couple of grays. My horse corral has been decimated, and my favorite is also gone. My chicken and pig pens have a fraction of what they had just last night. Doors are missing from my place and my friends places as well and can't be replaced (I added this fact to a separate bug report that had already been filed on the issue.) And I'm not sure, but it sure looks like my village is deprived of more than a few villagers.

Is this because I went so far away from my farm? I ask because when my friend came to get me from the Woodland Mansion, when we got there her livestock was likewise missing.

I don't have this problem going to my second place only a couple of thousand blocks away, but does the greater distance have something to do with the despawning?

migrated 2017-10-20T22:16:21Z

For us the issue is very new since the Better Together update. Never had any problems with that before. But now, many many animals are missing, even though they were in a compound.

Since the Better Together update we played mostly in the Nether, maybe it has something to do with that, but no idea.

It just needs to be fixed. It's a really big issue in survival mode.

migrated 2017-10-21T17:09:39Z

Been playing on a realm. Had two donkeys and four very fast horses fully secured, saddled, and armored up. After a few hours building in the same chunk, I now have one horse and one donkey left.

Can confirm this is occurring on Xbox One Bedrock edition - Realms. It occurs even when not interacting with a Nether Portal. Pics, Sheep and Cows that have been bread despawn. Horses, lamas, donkeys despawn after interacting with them. Occurs after logging into a realm (no interaction with nether portal).

migrated 2017-12-22T01:37:41Z

I'm also having this issue with a realm I'm paying for on xbox one. two out of four horses with saddles, and all but one cow that was bred were gone after sleeping in game. later, most of the sheep had vanished while I was in another part of the world(not far at all) fishing and killing mobs. All of these animals were in pens, and nowhere to be found nearby.

migrated 2018-01-06T17:40:26Z

I have noticed this on my server. However, I can never reproduce it myself (I am the server OP). It only happens when other players (non-OP's) log in and spawn in a place out of range of the entities in question. The entities are in a testing area. So I currently have two hypotheses: either they won't despawn for me because I own the server or since I am the one interacting with them, they won't despawn for me but will for players who haven't interacted with them. Although the latter sounds more plausible, the former is more likely because I have a semi-auto cow farm that the other players often use (which of course requires feeding the cows). If the latter were true, they would not despawn for anyone because they have been interacted with by everyone. However, they do despawn anyway.

migrated 2018-01-07T04:03:55Z

I was logged in and the entities were there. My wife logged in and a bunch of the entities disappeared (especially minecart hoppers, which is quantifiable and easy to notice missing). I made her and the other person on the server OP, and so far so good. I will keep you all updated in the following days if this works. But if it does, then I believe the issue is that they don't despawn for OP's but they do despawn for non-OP's.

migrated 2018-01-10T03:47:13Z

Ok, after several days with all members of my server with OP status, all of my checked entities have despawned (aside from one cow). So my hypothesis is incorrect.

migrated 2018-01-17T23:32:24Z

I've lost several parrots by leaving the nether and going to the overworld (those poor poor parrots). I'm the admin in my Realm and only my horse, donkey and cat have stayed in the world. Anyone else that has tamed an animal has lost it to a despawn. Our pens with sheep and pigs were lost to despawn, but the cows managed to stay? My villager breeder lost the breeders but the villager with the doors remained. The automated chicken cooker I made would lose all of the egg layers even though they're sealed in, come home to find a room full of chicken everywhere. I'm not sure if it has anything to do with how many zombies we spawn in at our zombie farm or not. Maybe I'll switch everyone to OP status like Joseph did.

migrated 2018-01-18T02:54:26Z

I would hold off on OPing your players. It didn't work. I'm hoping that the new update fixed it, but it is too early to tell. I know that when you interact with an entity, they get a tag called "Persistent" activated. It obviously doesn't do anything.

Confirmed in 1.2.10. Not just in iphone but in realms which affected xbox one. The despawn no matter how small the pen is and it happens when logging back in to realms sometimes. Seems way random but this should absolutely be a priority bug fix. Cant even justify paying realms with mobs in pens dissapearing ALL the time. Fences completely around but i have one sheep in a ditch 2x1 that hasnt despawned at all. This is thee worst. 8 cows and 7 despawned on 3 different occasions. Interacted with them fine.

migrated 2018-03-05T17:37:03Z

I am having an issue where my animals (Pigs, Cows, Sheep, Horses, and Lamas) are disappearing. First I had them in fenced areas, 5x5 areas, with one gate and no adjacent blocks or methods of jumping out. After loosing all my animals over two days (no remains, no mobs or creepers) even though they are safe inside my base with more than enough lighting, I tried something new. I started tying my animals up with leashes to the fence posts. At first this seemed to work, but then on the 3rd day, half my cows disappeared, one horse disappeared, all my pigs disappeared. My llamas and sheep were fine though. Mind you, these animals are in pens close to each other, and while a horse disappears, the other two with it are still there and unharmed. For the animals that disappeared and were tied to the fencing, the leash was still there tied to the fence, just no animal. I tried to collect the leash from the fence, and it just disappears when I tried to collect it.

These pen areas are roofed / covered, so I know it is not lighting.

This is very frustrating as I use to have a nice collection of animals when I brought this game from the 360 version over to the bedrock edition. Now I cant start a small collection. I am in survival and have never broken that, but trying to survive and not be able to collect animals for breeding and supplies is completely hampering my ability to play at all.

I am looking forward to hearing from you regarding this matter.

We've been having a similar issue on our Realms server we've recently made.
We started the trial because it sounded like a cool investment to play with our friends.
Two of us play from the Xbox One, of us plays from Windows 10, while the 4th plays on one or the other sometimes.
We've noticed horses and llamas frequently disappearing after the Realm resets or when anyone logs on. Usually the animals disappearing are fully armored, saddled, or dressed. But their offspring also disappears.
Its only effected llamas and horses most apparently, though a few cows have gone missing too.
The animals are all in smallish pens made with fencing (smaller or exactly the recommended size) and sometimes partially covered. They all had grass and water blocks and there is never more than 4 animals to a pen.
The pens are also spaces out with wide paths between them, but the animals still disappear.
We've lost at least two fully armored and saddled horses and at least two horses with just saddles and a baby.
As well as 6+ dressed llamas and babies, both fenced in and tied to posts.

We really hope it gets resolved. We don't want to pay for something if all our hard work just gets dumped at the end of the day.

migrated 2018-03-14T20:29:57Z

I am having a similar issue on a realm, but my animals seems to be disappearing based on location. I have two separate areas on this realm, both of which are in different 2048x2048 maps, and they are a good bit away from each other; a 2048x2048 map or two in between them.

Location 1 is near the spawn of the map, as well as other people's areas on the realm. There have been no issues on animals despawning here.

I like to travel so I built up a new area, roughly 4,000 blocks south and 3,000 west of location 1. Here I found an amazing white horse, left it out in the fenced off stable outside, and one day it was gone, saddle, armor and everything. I then found two black horses and brought them back to this location 2. I bred them to about 7 black horses, and slowly they all disappeared to none. Somewhere in this, I also brought in two cows to attempt to breed them for meat and leather, and they disappeared. This seems to be happening whether I'm offline or doing something on the realm, and I have not entered the nether like the OP of this post.

So eventually I traveled again, about 1,500 blocks north and 500 to the east of this location 2. These two areas are on still the same 2048x2048 map. I did a similar thing to where I found 2 horses and bred them to about 8 horse. Now I am down to 4 as some have disappeared. These horses are housed in large area outside, with two sides being a fence, one side being a large wall with towers, and the fourth side is not fenced but it is a large ocean.

A solution to this issue would be much appreciated, as I have found 2 near perfect horses and both of them just disappeared with the gear and everything, it is extremely frustrating.

Thanks,
Nick

So far no one has found a solution. I'm hoping it will be included in all the fixes planned for 1.13. I have honestly stopped playing until they fix it because it is game breaking.

Still doing this on my realm. Had 3 sheep last night. Had 1 this morning and the cow was also gone

I had several horses that I interacted with (bred, fed, saddled, armored) and that despawned in Bedrock Beta 1.2.14.3 and 1.2.14.4 on Windows 10 recently.
One despawned in the Nether while it was enclosed with fences, two in the Overworld also enclosed, and a fourth one disappeared after I pushed it through a portal (Overworld->Nether).
No drop, they just disappeared for no reason 😞
It's sad when you spend a lot of time to find good horses, equip them and then they just despawn...
I hope this will be fixed in the next stable release.

Thank you for your report!
However, this issue has been closed as Won't Fix.

Entities can end up being lost if they happen to be positioned on the boundary between two chunks when the game crashes. Unfortunately there is not currently a straightforward (or safe) way to prevent this from happening, but crashes are continually being worked on.

(Although it's not an ideal solution, one potential workaround is to position mobs away from chunk boundaries; further help with this can be sought through the community forums linked below.)

I respectfully reject the supposition this bug is caused by being on a "boundary between two chunks when the game crashes".

The issue appears on "Realms" servers and there is no "crash" involved. The server does not stop. Users (multiple) are not kicked out of the Realm. Gameplay continues without incident.

My continued experiences with this issue going all the way back to July 2017 occurs when traveling between the Overworld & Nether. And it repeatable every time. Animals who have been interacted with and are in pens will disappear. Named horses with armor and saddles will disappear, paintings will disappear from houses.

Respectfully I would ask that this be given a second look. This bug has made the game unplayable for my family as we are tired of having hours and hours of work wiped out by just moving between two worlds. It is almost impossible to overstate the importance of this bug being fixed to the many users listed here.

Independent testing by users seems to indicate the issue has something to do with the spawn chunk not being loaded correctly when switching between Overworld and Nether. It appears that if you move approximately 20 chunks away from the spawn the issue can be mitigated slightly.

There is also a possibility that animals are being teleported away as reported here:
===============================================
Today while traveling in my world in some area I didn't go since the event, I've had the surprise to find 3 tamed horses with their saddle and armor equipped. They are the horses I had before they disappear with all other animals... 5 pigs and 3 colored sheep were there too...

Could it be that our animals were in fact "teleported" in other chunks ? (or rather attached to the wrong chunk)

I'll try to see if I can find my 8 llamas somewhere else (easy to recognize: they all wear colored carpets)
===============================================

migrated 2018-04-04T16:29:56Z

I also respectfully reject this response as well. No where is it said that the game "crashes", my issue has been going on for years and it has never involved a game crash. I place my animals in their pens, feed them, breed them, gear them, and when I either come back from the netherworld or reopen the game after leaving, the animals have despawned. Often leaving leashes behind, but all other gear or equipment gone with their disappearance. This is happening in Minecraft Bedrock edition realms with my friends, so far each player in my realm is experiencing the same issue. Again, no crashes are occurring.

migrated 2018-04-04T16:33:27Z

Respectfully, this is not a resolution. "Won't Fix" is not acceptable to me and I would bet many other players. You closed 30 plus tickets that are all saying your game has a problem. Deal with it. This attitude is why I am abandoning Bedrock. Thanks for the fishes... almost.

PS My realm does not need to crash for your code to forget where entities are and despawn.

migrated 2018-04-04T16:40:26Z

This is not a solution or a fix. This issue is a major gameplay issue that has been going on for over half a year now, and simply marking it as "Won't fix" is not acknowledging a major issue with the game.

migrated 2018-04-04T17:41:29Z

As Brandon said, animals dissapear when you travel to the nether and back. Complete farms disappear. Yes there is also a bug were individual animals are disappearing but it is less frustrating then this one.

I used to be a customer for months on realms. I have stopped payments and ended my realms due to this bug and others. I now play the Java version of minecraft. I consider this a huge bug and therefor do not play on bedrock again.

migrated 2018-04-04T17:46:46Z

Sorry, but This is not a solution or a fix.
Respectfully I express all my disappointment for this "solution"
I ask you to reconsider the closure of this bug.

[Mojang] Mega_Spud (Jay) 2018-04-04T17:51:23Z

Reopening this for a further review, especially if this is not based on a crash occurring.

If anyone can offer a video showing the animals despawning after using a nether portal it would be appreciated, as it has not been easy to reliably pin down the bug.

migrated 2018-04-04T19:23:46Z

Mega spud, my despawning issue does not involve the nether, seems more based on which chunk I'm in. Definitely not crash related either.

migrated 2018-04-05T02:04:59Z

i have posted on others and now i am directed here.
realms, two players experiencing problem. sorry no pics or vids.
the entities (sheep, cows, villagers, etc) disappear on us when loading back into the world from a logout. not a crash - a regular, end of day, logout. i have set myself looking at my farms and a healthy farmer when i logged out and when i logged in the next day that farmer was missing. it doesn't happen every time. with 3 farmers running i would lose one of them every other day on average.

with my own testing i find it is entities that are allowed to roam in larger pens that disappear such as cows or sheep in a 5x5 pen or other similar size and also farmers ranging in farms of 9x9 or 9x18 pens. i never lose entities penned up in a 1x1 cell. i have 30+ villagers penned up in 1x1's and have not lost one to this bug (lightning being the only issue of villager loss in a 1x1 pen.)

so now i have to lure my farmers into a 1x1 pen before every logout or i risk losing them. if i do not pen them up my farmers will not last a week playing once or twice a day. while this solution is working for me it is an inconvenient waste of my game time and it is not the permanent fix i'd like to see.

i can't confirm whether or not it happens when going to the nether or the end and coming back. i'll have to start paying more attention to this part.

migrated 2018-04-05T08:28:24Z

I can confirm this is still happening exactly as ian has said this, we play on a realm, farmer villagers are the biggest problem due to the effort in getting them back, it doesn't happen when they are in mine carts so I just do that for now, sheep and cows are easy to breed back up but losing 20 a time is a pain, I have now noticed that if u travel to the nether or end while the entities are in your loaded chunks i.e the 4 chunks around me (on realms) it can happen immediately, I lose both my minecarts with hoppers everytime and with them being underground under my farm its a nightmare to put them back, I have resorted to putting a nether portal 180 blocks away from all my farms. This works as the chunks are not loaded, so it seems to only happen when the chunks are loaded. (Edit: I interact with all my entities daily as feeding or trading) Windows 10 Realm 1.2.13

migrated 2018-04-06T19:22:17Z

I can also confirm this has started happening again. I lost three out of the eight villagers I had cured from zombies while completing construction on the village to enclose it. I also lost 1 of my six horses and 4 of my 12 sheep, and the cow and pig population (which I don't keep count of) was similarly depleted.

migrated 2018-04-15T23:33:15Z

Happened to me recently on my Realm, fwiw. Discovered a village full of villagers near my spawn point, interacted with some of them, then traveled a handful of chunks away (the length of a map, give or take) to grind for trade items. I returned to the village about 20min later, only to find that it was completely deserted! Doors on every house, difficulty on "Easy" so zombies breaking down doors shouldn't have been an issue. All the villagers just seemed to disappear!

migrated 2018-05-04T11:32:03Z

I had lost half the horses in my herd when I logged in last night into my survival hard realm. Then through the course of playing for the evening, I'd lost half the remaining herd.

These were all fed, saddled and tested horses (I have a test track for speed and jumping), two of which were named and armored.

Now, to make matters worse, horses are sinking into the ground and dying right in front of me. Solid ground, and they are just dropping into solid blocks of dirt and suffocating with only the tops of their heads visible sometimes as they take damage and die. You can hear it more much more often than you can see it.

Can those who have experienced a lost please try providing the following information?

Turn on coordinates

Give the coordinates of where your nether portal is,

Give the coordinates of where your animals dissapeared

Give the coordinates of where the portal in the nether ends up

Give your render distance and simulation distance

I mainly want to see if there is any correlation between coordinates in the nether and coordinates in the over world.

migrated 2018-05-18T13:13:57Z

I can't turn on coordinates without turning on cheats on our realms. 😞

However, we had tamed/saddled horses and blanketed llamas disappear both very close to our nether portals and almost a KM away too.

Our portal is somewhat close to spawn as well, if that's important.

And all our users have different render distances, I'm guessing.

migrated 2018-05-18T19:58:50Z

I thought that too, but all you do is download your realm locally. Go to the local versions settings and switch on coordinates then re upload that version of that map on your realm

Happened to me in single player not on a realm at all... 2 villagers both of which I had just opened trading windows with but not actually traded so they had been interacted with but were spawned from spawn eggs. Both within the area of 191,166,214 and 218,157,186 ... This is within a set tickingarea, used a portal at 244,169,324 leading to the nether at 30,70,42. Returned from nether to find them both instantly gone. But 6 other villagers in the same area were still there. This is on Xbox one 1.4.2 ... I have a feeling this might be related to the mobcap as have lots of other mobs both passive and hostile in the tickingareas and possibly am over the 200 limit even though most have been from spawn eggs, but has only just started to happen as I built more farms. Have also had a snow golom disappear which had been sheared of its pumpkin and name tagged recently. Oh and render distance 22 and simulation distance 10... But has happened at render distance 10 too

migrated 2018-10-30T05:35:25Z

I experience entities disappearing through nether portals, but only when a player is on both sides of the portal.

Example: If I push a villager into a nether portal from the overworld, and all players are in the overworld, then the villager will appear in the nether without issue. If a player is by the nether portal in the nether, then the villager will not appear in the nether. This occurs for any entity.

Device: iPad mini 4 (Model FK9P2LL/A)

OS: 12.1.1

Minecraft version: Bedrock 1.11

World Seed: 1970374129

Mode: Survival, Normal

World Spawn: 233, 69, 12

Nether Portal – Overworld: 90, 63, 24, Nether: 4, 62, 1

Sheep Farm: 140, 64, 13 x 148, 64, 20

Horse Corral: 243, 70, -124 x 245, 70, -129

Broken Zombie Spawner: 237, 60, -123

Player-Created Village: 245, 70, -133 x 212, 70, -109

What happened: Almost all the sheep and the horse despawned.

Additionally, all the villagers that I had interacted with previous to this release retained their professions with their current level of training but then despawned after I'd attempted to use the new game mechanics to set up work stations for them, but I am assuming that is "intended" behavior for a player-created village or else a bug related to Villager mechanics.

I am not sure about when that happened relative to any trips to the nether, but I don't think that this was before I went. I had just updated to Bedrock 1.11 and was spending time trying to understand villager mechanics so wasn't going to the Nether. That said, the game crashes every time I background the game by closing the cover on my iPad. It took me a while to figure out but I suspect it is crashing in part due to the lag caused by MCPE-42427 (in hindsight, locating a village directly above a zombie spawner was perhaps not the best plan - oh well). Unfortunately, I did not make a copy of the world prior to updating (I have automatic updates turned on). I also have not had time to implement the suggested work-around so all the spawners are going crazy overtime. (This world has several deactivated spawners in it that are all located right around my farm and world spawn.)

Hope this helps.

[Mojang] Mega_Spud (Jay) 2019-05-15T09:47:51Z

@unknown - In the two examples you have shown, it looks like the pens are directly situated on chunk borders, which I have marked in red and green here:

[media][media]

If the mobs are located on these areas when the game crashes (or the Realm/Server stops) then the animals have a high chance of despawning (which is the bug at play here).

The workaround is to locate the chunk borders, and then move the animal pens so they do not cross any borders.

Each chunk is 16x16 in size, and you can calculate where the chunks are positioned. One easy way to calculate and visualise the chunks is to use a site such this and enter your coordinates: https://depressed-pho.github.io/slime-finder-pe/#0,0

migrated 2019-07-01T17:58:06Z

I'm not sure my issue MCPE-47922 is a duplicate. I did interact with the horse at least, and my game didn't crash during any of the days I spent in it. Also, all of it happened after the update to v1.13.0.1 Beta. Did you have a chance to look at all the details I gave in the description?

migrated 2019-07-04T23:00:04Z

All of our farm animals despawned and we just interacted with them last night. All of our sheep had name tags as well so they were named mobs. Pandas, cats, dogs, cows, pigs, fish, horses, llamas, and sheep are all gone. We are also getting a ridiculous amount of angry mobs spawning inside of our house that is well lit and outside which is also well lit.

Edit: Coming back after my level 3 Cartographer (The one i mentioned before lvled up) disappeared. No patterns with Novices. Still extremely annoying.

In my world, they despawn everytime the game crashes. And my game crashes a lot.

migrated 2019-07-21T08:44:20Z

So the temp solution is to... position them on chunk borders that can only be determined by turning on coordinates... But what about if the game DOESN'T crash? because this happens whenever I just log back into a world. Quite annoying when youre wasting Gold to make Golden Apples to cure villagers only to have them despawn the next time you log in. Making the adjacent Splash potion of Weakness takes less resources but it still a waste if theyre just gonna despawn. This bug has been around for quite a long time.

So I commented on a similar thing, and doing so here to for better visibility. Me and my roommate are playing Minecraft Xbox One Bedrock Edition Beta, and while achievement hunting, we finished the Plethora of cats just recently, and I was helping them with getting the renewable energy. After they used charcoal to smelt wood into more charcoal, the achievement never showed up as complete, so we waited about 1-2 hours, then we saved and quit tried again, but when we logged back on, our 25 cats, our fox (which was gone before due to same issue), and our donkey (at least) were all vanished and gone from the game. We still have our Iron Golem that we made along with completing the Plethora of Cats Achievement, but everything else is missing (animal wise). I've been to the nether last time I played (when I got the fox and the fox never Despawned when we both were in the Nether and came back. Nothing happened on that front.) So the Nether DIDN'T CAUSE MY ANIMALS TO DESPAWN!

It happened to me and leave the world to return back to Java Edition, because it's very anoying.

Details around whole world story

I have a trading center, and one time decided to release villagers, to leave them free around the trading center (coords: 258, 67, -102 ). I have no problems for hours and hours of gameplay, gone many times to continue trading stuff with them. But one day I was working on a Pillagers outpost to make a pillagers farm. Come back to my house, visited the trading center and Oo.... I've lost 6 villagers of 14. My trading center is walled, lited and it has a roof to avoid thunders... so these villagers has dispawned for some random reason.
Another thing... I've lost 5 horses. 1 of them even being in a closed area (coords: 346, 68, -107).

My Nether portal is at: 381, 70, -52

I had some game crashes, but not frequently... I mean maybe 1 crash in 30 hours of gameplay.

This information is related with singleplayer mode

I put nether portal coords, because in some comments I've read that it could have any kind of relation. I hope this thing helps to fix this issue.

Do the chunks all save at the same time? If not, that would explain the bug. Suppose chuck A saves, a mob from chunk B comes to chunk A, chunk B saves, and the game crashes before chunk A saves again. Then both chunks would have been saved without the mob.

I think a similar occurrence could cause mobs to duplicate. Has anyone observed this?

I'm playing Windows 10 Bedrock Edition version 1.13.1 and I feel like this is happening to me, too. I've created pens for some of my animals, specifically sheep and cows. I'm absolutely sure I've bred them multiple times, but when I went to check on them last time, I only had two cows and one sheep. The game has crashed a few times, so I think this ticket fits the issue I'm experiencing. I didn't test to see if these animals were on chunk borders. That might also explain why I can't seem to find the iron golem that used to be in the village I live near. I may have to do more testing and get a screenshot of how many animals I have now and if it changes, I can provide that.

Ok, so I attached two screenshots. One shows you my tamed horse in the pen, the other shows you that my horse disappeared. The game did crash in between these pictures, maybe a crash log could provide more information, but I'm not sure where that might be. Also, I bred some more cows, the game saved, then crashed, but my cows didn't disappear. I'll see what I can find out about the game crashing. I know it does this sometimes if I minimize the window. Perhaps I should save and quit instead of minimizing the window.

PS4 Bedrock Edition.
Single-player Survival World, newly created after the update.

Case 1: 3 villagers vanished from my iron farm. My only nether portal at the time was over 200 blocks away. The game had not crashed, but was saved and closed as the PS4 went into “rest” mode. These villagers are now under glass and cannot move around, none have vanished since then.

Case 2: a name tagged panda that I had bred from two others, and subsequently bred as well vanished from the fenced enclosure it was contained in. The game had not crashed, but had been saved and exited via the menu. There was a nether portal nearby, that I had used.

Case 3: returning from a more distant part of the world I found that my trading hall villagers had bred a replacement for a missing librarian. Some time later, I used my nether portal and found said librarian in the nether.

In the last 10 days I have experienced 2 crashes, but I have saved and exited my game once or twice a day, I don’t think this issue is related to game crashes at all.

Since 1.13 some of my villagers have been despawning as well, and I am 99% certain that they weren't killed since the entire village is protected by walls and is completely lit up. At first I thought they were stuck somewhere but I have looked everywhere and now I've concluded that they have just simply despawned for no reason.

And this happened again like literally today (on v1.14.1) as I had a cleric villager and a couple fisherman villagers that were present a few days ago but as of today they are nowhere to be found.

This happens to me in my large world which crashes often. It happens mostly, to my knowledge, during crashes, and it has happened with three tamed, saddled horses and a named slime, none of which should ever despawn.

migrated 2019-12-31T04:24:55Z

Happens to me after crashes, which happen very frequently. I lose animals/pets and oftentimes have to fix redstone circuits. Really annoying bug. I am on PS4 if it matters.

UPDATE: Another NAMED slime just despawned. It wasn't even in loaded chunks. I'm getting seriously fed up with this glitch. So far I've lost three saddles and a NAME TAG to it. Not that I should be emotionally invested in this, but I worked hard to get where I am in this game and it really, really frustrates me to slowly see my hours of progress be destroyed by a 2.5 year old glitch that means nothing I do is really safe. PLEASE, PLEASE, PLEASE prioritize fixing this.

I'm pretty sure a couple of my villagers despawned too, including my EFFICIENCY V Librarian.

And this does affect v1.14.1.

In addition to providing updates in this bug report, it is worthwhile to rate the game in the Microsoft Store and ensure your rating and comments reflect the negative effect this bug (and others) has on your enjoyment of the game. Due to this bug and the lack of hostile spawns (MCPE-21856) I haven't played Minecraft in probably a year. I keep up with the Jira updates, but so far it seems that the bugs aren't hurting sales so they're not really getting significant attention.

GoldenHelmet 2020-01-07T20:35:53Z

I have experienced this bug with animals, iron golems, villagers, and hopper minecarts in various worlds, times, and places. I only play single player and cross-platform multiplayer, no realms.

I hope it is clear to everyone by now that:

Realms are a red herring,
Crashes are a red herring,
Nether Portals are a red herring.

Entities disappear because of a general flaw in how chunks load and save. Realms, crashes and Nether Portals simply highlight the problem because they involve a lot of chunk saving and loading.

I have read all of the comments above and the most intelligent point is made by @Blobs2. It bears repeating:

— Suppose chunck A saves, a mob from chunk B comes to chunk A, chunk B saves.... Then both chunks would have been saved without the mob.

Blobs2's comment above included a reference to crashes that I have replace with an elipsis. For in fact, any event that removes chunks A and B from memory before they get the chance to save again will result in the mob disappearing. Crashes and traveling to the Nether do this, but so does general travel, when chunks are no longer in your simulation distance. That is why a lot of people report entities disappearing when they have traveled away and then back to an area. It's also why you see this more on Realms where there are more players travelling around more places, causing more chunks to unload from memory more frequently. The randomness of mob movement related to the exact timing of chunks saving and unloading would also be why this is so difficult to intentionally reproduce.

I'm not sure how this could be solved. Perhaps a tweak to the order in which chunks are saved could help, or some kind of adjacent-mob-check before a chunk is unloaded, or adding some kind of mob-location-history data? Maybe it can't really be fixed without a fully redundant, non-chunk-based, global mob tracking system for mobs with permanence?

I also am losing villagers especially librarians and farmers in a single player world.( actually it is set to multiplayer and my husband joins me on my world thru our network but was specifying that i am not on a realm) These are ones I have traded with. I have a pile of villagers now with no profession that also seem to not get a profession.
I switched to peaceful and got the librarians ( 13 of them) to trades I wanted and was in process of levelling them up. (all at level one or 2).
I went to another village where i had 3 more librarians including a mending one and to the nether and when I came back to the first village I only had 6 of the 13 librarians left, I am not sure if they are just unassigning or what, as I have a pile of unnassigned that keeps growing in number which never seem to choose a profession even when right by the lecterns which is why i wonder if some of them were librarians. I have not moved the lecterns. Have lost several mending librarians at this village which is particularly annoying as I spent a lot of time getting them and starting to level them up. Also in other villages I have found villagers disappear too. I had thought in those other villages they were being killed by monsters but since it is happening in the 2 villagers close to my house and also when in peaceful it seems they are either despawing or becoming unassigned villagers and losing their profession that wont chose a profession now they have been traded with

GoldenHelmet 2020-01-12T03:32:50Z

Perhaps this is related to MCPE-55092? The common thread would be funky stuff happening at chunk borders. There has to be some kind of memory overflow or read/write target error going on with chunk saving and loading that affects things on the borders. Like maybe the data for the blocks on a chunk's border can get overwritten by the data of the neighboring chunk in certain situations.

There are also many reports of light not updating from one chunk to another such as MCPE-60586 and MCPE-58182. In this case the chunk saving algorithm is losing data it should be keeping, or else the chunk loading algorithm should grab data from neighboring chunks but it does not.

I just want to suggest that all these things could be related to a core problem with memory handling for chunk saving and loading, but which does not show up every time. Some kind of calculation that overflows memory space but only with certain results maybe. I'm not a programmer but I have enough background and sense for things to suspect something like this is going on. I hope someone investigates this possibility.

migrated 2020-01-15T22:05:12Z

I’ll throw my experiences in here as well. I’ve had multiple villagers (taken from a village,born,cured,tagged,not tagged) vanish for seemingly no reason. Sealed up in a well lit building. When I replace the vanished villager with a new one, the new villager will not claim the empty bed or work station until I break those items and place them again. Also has happened to bees and horses.

GoldenHelmet 2020-01-15T22:53:10Z

@Nicholss Otto that sounds like an important clue about the beds and workstations still being claimed. It reminds me that in my current village, the two iron golems have disappeared (and I know they did not wander away b/c the whole place is fenced carefully to prevent just that, since they did wander off early on) and the village will not spawn replacements even when I corralled and slaughtered all of the cats. It is like they are still in memory somewhere but not functioning at all. It is very much like the bug with beds going invisible and unusable until you break and re-place them. I’ll have to check if my bed is on or across a chunk border, b/c that one has happened half a dozen times in this world, and never in other worlds.

Update: my bed does indeed sit across a chunk border. Z values are 224 for the foot and 225 for the head. @Nicholas Otto I doubt it has anything to do with seed. It is all about chunk borders.

migrated 2020-01-16T03:07:12Z

@GoldenHelmet, I was curious if this bug could happened more frequently in certain seeds. Never seen it before, but also don’t feel I ever got this far before in developing a world. It’s kind of a bummer, but I might abandon my current seed and hope the next world is a little more stable.

migrated 2020-01-17T16:47:38Z

Two things about the chunk border idea (which I think is a strong possibility) which make me go "hmmm..."

1) It's hard to see how multiple entities would vanish at once if it was a border issue. If the idea is that Chunk A is saved, entity X in Chunk B wanders into Chunk A and then some time later Chunk B is saved (poof X has disappeared), this would mean that people who notice 'several' villagers disappearing at once would have had all of those villagers wander over a chunk border at the same moment?

Alternatively, there must be a long (not milliseconds, more like seconds) delay between adjacent chunks being saved. Maybe the player moves just far enough away to cause Chunk A to save, but Chunk B stays active for a while until the player moves just far enough for Chunk B to then save?

I can easily see a chunk-border-related chunk save timing issue poofing entities one at a time over time. But groups of them all at once? Harder to explain.

2) Useful test: build two animal pens, one entirely in a chunk, one spanning a chunk boundry. Fill both with livestock. Run around like a madman, unloading and loading your animal pens as you move away/come back. Do this 1,000 times and report back the % of each pen that disappeared. Good luck we're all counting on you.

While there may be a chunk issue, I've lost an expert level mending librarian about 4 or 5 blocks away from the chunk border at his closest reach.

I created a village of 3 buildings with 4 villagers. I've been having a constant issue with villagers despawning. Originally got up to 3, 2 disappeared, so I went and grabbed more, the last one of the remaining 3 despawned. I consistently had this issue and I lost track of who I lost and who I kept. I built an addition to the side that ended up allowing villagers to stand on the wall and I wasn't too worried about it. At this time I had three villagers all brought in from the same grouping of zombie villagers.

I then some days later I grabbed another zombie villager for a mending librarian. I locked this one into a house. He had 7 total blocks within his blocked off area. The closest block that he could stand on to a chunk border was 4 or 5 blocks away from either horizontal chunk border. Of his 7 total blocks within his area, two were used up for a "bench" made of oak planks with a brewing station atop one, the workstation for librarians (escaping my mind right now) is taking up another block but not on the ground, just floating. and then of course he had a bed in there. this area is 2 blocks high.

I do have a Nether portal within render distance, although I can't recall this last time whether I had recently used it.

The odd thing I've noticed is that with this last group, the villagers I brought in three at a time, all vanished at the same time. The librarian remained and I assumed it was because the other three could get up on the wall. I now assume that the same amount of time between when I cured those three and then cured the librarian, is the same amount of time it took for the librarian to despawn although this was not me actually testing it out but rather just trying to play and these are the observations I made.

I wanted to throw this in to make the point that the chunk border didn't have anything to do with the last one although it could've with the other three if this were caused by two different issues.

Edit: Forgot to mention, I am playing on Xbox One.

migrated 2020-02-06T12:31:42Z

I lost a Librarian villager with Mending to this bug. I had a nearby nether portal, not sure if that is related to the bug or not. I don't know how to calculate chunks, so I am not sure if my villager was lost due to a chunk related bug. I traded with that villager fairly recently and did not travel too far away from said villager.

GoldenHelmet 2020-02-10T20:36:40Z

@MD I actually set up a flat world to test the "crossing chunk border between chunk saves" theory. I set up slime blocks on sticky pistons to knock a horse back and forth across a chunk border, and a minecart carrying Binky the rabbit around the whole thing, and I went in and out of simulation distance, and in and out of the nether. Finally I set up a 500 block long minecart loop that would take me in and out of the simulation distance and in and out of the render distance for one or both of the chunks the animals were passing between on every other loop up and back. Let it run a couple hours and did not see any despawns. So I'm thinking it isn't exactly crossing chunk borders that leads to despawns.

I wonder if mobs despawning, chests and beds going invisible, items despawning from item frames, and block textures going invisible (where whole chunks go into x-ray vision) may all be related? The pictures and reports suggest that often everything of a certain type within an entire chunk will be affected–as if one loading error propagates across all data of its type within a chunk. The missing textures/x-ray glitch also seemed to propagate from chunk to chunk in a recent experience I had with it. (Fortunately, it resovled after relogging. My iron golems finally came back too, after about a week and after I broke and replaced some beds.)

Maybe the bug is actually in the way chunk data is processed, rather than how it is saved or loaded per se? Something to do with optimization, perhaps?

migrated 2020-02-11T09:19:52Z

On Xbox Console Edition, we used to have this problem until devs made mobs become more physical rather than transparent when they moves through the player. Instead, mobs were solidified and were able to push the player, even the passive ones can push you. It wasn't fully solidified in sense, mobs can still glitch through if we walk against them at full speed. It got solved really well for a few months if I remember correctly before Bedrock took over.

Edit: villager riding in minecart can bounce from the player standing in the way.

I am not sure if that was the case but other thing I noticed that the chunk get loaded first before the entity rather than load everything at once. That's all I can say.

Slight copy/paste from elsewhere. My issue didn't relate to Nether or chunk loading but seemed to be to do with stopping/starting the server. I was in a village on a new world (minutes old) and stopped/started the server a few times. All villagers but one vanished. I fenced him in his house (with bed and workstation) and lit it well to keep him safe (because I assumed all the other villagers had died) but he has also now vanished!

edit: I find it hard to believe that approx 8 villagers, spread out, were all on chunk boundaries at the same time!

migrated 2020-03-14T22:13:58Z

That depends on what the root cause it (is it related to chunk borders? does the nether have anything to do with it? are these the symptoms of multiple causes that are making tracking down the bug/s more difficult? etc).

Once the cause is identified, then it’s a question of how it can be fixed. Let’s say, for the sake of argument, that the cause it entities crossing chunk borders between saves. Chunks don’t save simultaneously to reduce processor strain. So how do you fix the problem without introducing massive amounts of lag, or unexpected/unwanted behaviours?

I anticipate this issue is going to take a very long time to fix, but that’s just my opinion. I’ve taken steps to prevent it as best I can, by corralling entities into small areas (horses are penned in 2x2 stables, instead of roaming in a paddock, villages are trapped in a 2x1 area that fits them and their bed. It’s not ideal, but it does seem to be compensating so far.

I have experienced having my villagers and other mobs despawn for nearly a year, I first commented on this back in January however it is still occurring. I cannot level up a villager because they usually despawn before I can max them out and even if I do they still disappear. I was told to avoid chunk borders but irregardless of where they are they still despawn. I have read that mobs must be interacted with, but I have had leveled up villagers simply disappear.

They are not drowning in the well, they aren't falling in a canyon, they are not being killed by zombies or pillagers. Just disappearing. I tested this by building a small village of 7 villagers I left for a moment and came back within less then 30 seconds I had already lost 1, within 5 minutes only 2 were left. A day later all were gone.

I cannot build a lasting village, I cannot farm animals, simply put I cannot play the game. As I saw a previous comment state, please fix this as my favorite game has more or less come to an end. The older version had tight population limits but at least you knew your villagers would be there when you came back from mining or cutting some trees.

Workaround

Never move further away from your village. To go exploring, build a nether portal close to your village and use only this to travel to and forth your village. Once in the nether, travel a long way away from that portal. Place marks along the way or even build a road to ensure you will find your way back. You even can bring a horse to speedily close the distance. Only when you are far away from the first portal, build a second portal to exit the nether. Return to the surface to go exploring, but do not travel too close to your village whilst under the sun.

Always create a backup before you start playing. If the game crashes while you are close to your village, quit the game and restore the latest backup.

@Shannon - what we are referring to is the initial reporting of this bug, from April 17, 2017. There are ~160 comments stretching back that far and 360+ other related reported bugs. As Dr.Awesome said in his warning to me, it is a complex problem and has been with us for some time. I did not experience the bug when it was first reported, but was hit several times in 2018-2019 before I put the game on the shelf.

@Dr.Awesome - I take your point. The Helpers here have done a lot of different tests and posted their results. Even yours truly has posited some constructive ideas (or so I thought at the time). However I should not just post complaints. If you happen to know of any particular corner of this issue that the devs would like us to play with, I'll go play with it and try to be constructive again. This plus the #1 voted bug has kept me out of the game for a long time, but I'm fine going in and running particular tests. Feedback about what the bug might be and what it is not would be helpful, so we don't rehash the same topics (i.e. Nether portals).

GoldenHelmet 2020-04-13T20:10:26Z

It may may be of interest to those of you concerned about this bug–and may help in your own attempts to reproduce it–to know that I have recently reproduced one specific kind of despawning: MCPE-51837 (Horse/Boat/Minecart you are riding on disappears on relog). I was able to cause ridden entities to despawn with the right combination of movement, autosave, and crash simulation (closing the game with alt-F4). By Looking at the chunk data, I was also able to determine that the specific bug with ridden entities despawning occurs during the saving process.

On the other hand, I have recently reproduced some specific chunk-border-related bugs that occur during the loading process: MCPE-48054 (redstone dust can lose its connection to solid blocks across chunk borders when reloading), and MCPE-67479 (cocoa pods on chunk borders can break when reloading). I am also sure that invisible beds occur on chunk borders during the loading process, but I am still working on documenting that.

It is possible that both saving and loading issues, as well as both chunk-border-related and non-chunk-border-related issues, have all be linked to this ticket. I'd invite anyone interested in trying to test and reproduce to take a look at what I've done on the tickets mentioned above.

@ricstrr thank you for the world upload link! I hope to take a look at it this week.

@Andreas G. two cautions about the workaround you've suggested:

Travelling in and out of the nether involves saving and loading chunks just as much as travelling over land, and if you look back at some of the earlier comments on this bug, some people have reported despawnings happening related to using nether portals.
Using nether portals near villages has been implicated in another bug, MCPE-49580.

@fundale that was suggested in a previous comment, and then critiqued, and many commenters have contributed evidence to support the critique. Tl;dr it could be the cause of some cases of entities disappearing, but it's probably not what's causing a great majority of the disappearances.

Re: Nicholas Otto's observation that new villagers cannot claim the disappeared villager's beds: that would be because the villager POI list still lists those beds as belonging to the missing villagers. The are 3 ways to unlink POI: (1) destroy the POI (2) the villager whose ID is matched to the POI fails to pathfind to it (shown by anger particles), or (3) a timer for the villager runs out before that villager can be found by the village. The timer can be >20 minutes.

GoldenHelmet 2020-04-16T19:41:03Z

I've looked at the world uploads provided by @ricstrr above.
1st save:

9 villagers listed in "dwellers"
2 of these villagers have not been "seen" for over 10 minutes (both show TS: 11528)
12 sets of POI with unique villager ID's.

2nd save, almost 24 hours of playtime later:

5 villagers listed in "dwellers"
1 of these villagers (a librarian) has not been "seen" for 13 minutes (TS: 16274)
9 sets of POI with unique villager ID's

These data are consistent with villagers disappearing from the world save and the village record taking some time to catch up.

The area east of the village where ricstrr said his wife was building is >200 blocks away, well beyond simulation distance. So, it is not possible that anything happened to the villagers while she was over there.

The world is set on normal, so pillager patrols could possibly have spawned close enough to the village to snipe villagers if a player was also close enough, but if they had, they would have gained persistence and probably been found, and ricstrr would have told us about that 🙂 There are no pillagers within the village walls in the world save.

tl;dr it looks like villagers have been steadily disappearing from this village when chunks are either saved or loaded.

More support for it being a chunk border issue - I built a stable with six stalls. The animals in two of the stalls disappeared, the others did not. I went back and checked the chunk borders - the four stalls that the animals remained were all within a chunk border - the two where they disappeared were across from each other and spanned two chunks. So it seems the issue lies in how the game is saving data - the because of the order in which it saves mobs are disappearing. A similar thing seems to happen on some of my crashes - sometimes I get a duplicate item, sometimes it disappears completely. If I place an item and then the game crashes the item disappears, if I pick up the item and then the game crashes it duplicates. In that case the surroundings save before the entity or inventory - so the duplicate happens because my inventory hasn't saved yet, but the surroundings have so the item (for example a bed) is on the ground and in my inventory when I reopen the game. Probably a similar issue to this

Items also randomly despawn when you're 54 blocks away, for some reason armours that was equipped (helmet, leggings, chestplate, and boots) were still persist, maybe because the game think that equiped item count as an interaction

The Villagers that I leave in this place always disappear, after a while I discovered that it is because of the chunk edge that passes right in the middle of the place. Detail: Villagers on the left and right do not disappear. I play on Android 9.0. My world is not multiplayer. I only play alone. Before I went to the Nether the Villagers were already gone.
I already put it in the pacifico to test it and even then the villager of that place disappears, and that made me confirm that it is the fault of the borders of chunks.

I remembered why I disabled auto saving in Console Edition for years before Bedrock. Auto saving caused multiple issues. When it was disabled, the game became problem free, experienced rare issue but will not save upon crash or freeze eventually.
I don't like auto saving and load/unloading chunks simultaneously.

Give us the ability to disable auto saving, with the options of save the progress and save and exit at pause screen. I don't mind longer saving progression at pause. 🙂 Like we asked for from the early Bedrock release long ago. This was available in single and multiplayer in CE.

Other solution that I have been doing since disable auto saving doesn't exist in Bedrock, is to make a copy before each play session. You lose less and time than having 1 original copy. I usually have 10 or more copies. Delete oldest saves when it is safe and keep few in hand.

migrated 2020-05-24T21:59:58Z

Yes, it will lose progress without save, corruption or losing mob won't occured. You have to make save manually at pause. I would rather lose 15 minutes to an hour progress between manual save.

I doubt it is possible on Bedrock due to the infinite world. The only way to do is backup routine.

GoldenHelmet 2020-05-27T19:28:36Z

I have a new theory on this, and I'll need some information to test it. I want to see if the random despawns are related to specific coordinates or chunks. I recently determined this to be the case for MCPE-44815, so I'd like to explore it here. If you have a certain structure of location where entities have despawned more than one, please comment with the coordinates and how many times mobs have disappeared from that location.

Also if you can provide a world save that would be great!

migrated 2020-05-27T19:49:34Z

My Villagers only despawn in that location. I've even lost count of how many have disappeared.

And in that place there is a chunk border, so that’s the problem.

@GoldenHelmet - I have linked a copy of my family's Realm world where we see the problem - I copied this from my Android phone backup of the world:

Family Realm on Google Drive

We experienced the disappearing stuff bug multiple times in this Realm starting just after this save.

1.) We lost livestock located at 50,x,7.

2.) We lost all the paintings in the house centered at 63,x,6.

3.) We built a nether portal about 100 blocks away. The provided backup unfortunately is before we built the nether portal.

As soon as we started traveling back and forth to the nether, we began to notice things disappearing sometimes when we returned. We also noticed, that although we always entered the nether from the same Overworld portal, and we left the nether via the same Underworld portal that was created, when we returned to Overworld we were always coming back to a newly-generated Overworld portal. We eventually had ten or more portals in the Overworld within a 40-block radius.

GoldenHelmet 2020-05-30T09:14:55Z

Thank you for the coordinates and world save.

@@unknown

villages have a timer for each dweller that unlinks the beds and workstations when they have not been “seen” in the village for 20 minutes. Breaking the bed/workstation or killing the villager while it’s in the village unlinks it right away.

I have been able to reproduce the villager despawning in a structure like the one shown in your picture, at those coordinates, by using alt-F4 to close the game after pushing the villager across the chunk border. However, it doesn't always happen, so I'm still testing exact conditions. I'm also testing other locations and it does appear to work on any chunk border.

@@unknown

It sounds like you're experiencing the version of this bug where entire chunks lose all of their mob entity data at once. I can't reproduce it locally using your world. It probably has some relation to loading lag when you come out of a nether portal on a realm. However, that could depend on the exact nether portal coordinates, so if you could get me those I'd like to test it.

The issue with creating new nether portals is likely not related. It is something that can happen due to how portals work. You mind find some help here: https://minecraft.gamepedia.com/Tutorials/Nether_portals#How_portals_work.

Now though, I had a horse grazing in a stable I just made. When I loaded the game thi morning, the horse was gone along with the armor. I haven't noticed it happen with any other animal though. Just the horses and llamas I have tamed.

When building an artificial village, place villagers in closed, well-lit houses so that mobs do not kill them, however some villagers have disappeared in the same way. This happened several times in different worlds, I already changed the location of the audeões and I took all measures to avoid escape and death, but still they disappeared with time. It is already tiring to replace villagers.
The places where there were villagers were places with high walls and closed to avoid arrows, well lit to avoid zombies, without doors to prevent escapes.

1.14.60.5 - Two chested and leashed donkeys despawned with items. Using a chunk reader shows they no longer exist. Since a lead can stretch, there seems to be about a 6x6 block safe zone within a chunk. 36 of 256 blocks are safe for a post.

migrated 2020-06-30T19:14:18Z

Hi everyone, when making an "I lost entities, too" comment, please include information about what happened and what you were doing at the time.

If you look at when this issue was opened (April, 2017) you will realize that this is clearly a very difficult problem that Mojang has been chasing for years. I know how frustrating this is and how upsetting it is to spend a lot of time trading up a villager, getting a fox to trust you, taming a wolf, etc. only to find that entity has despawned. If you play in a realm or on a server, this can lead to trust issues between players who suspect each other of griefing. I hear your frustration but this is not an issue that is going to be fixed with confidence any time soon. Please help those of us who really like playing anyway to figure out how to mitigate the problem. Thanks!

Information that is useful to include:

1. What version are you playing on
2. What platform (iOS, Switch, Xbox, Windows)
3. Type of entity (villager, door, etc)
4. Coordinates of the entity
5. If the entity can move, what is the corral made of (fence, solid block, glass)?
6. Did the world crash?
7. Did you go to the nether?
8. If the entity is a mob, did you interact with it in a way that should cause it not to despawn? (name tag, trade, feed, tame, etc.)
9. Did you "Save and Exit" or did you just turn off your device?
10. Did you move away from the entity and then come back (unload the chunk)?

Work-around for resetting villager trades:
1. Check your new villagers trade before trading with them.
2. If you don't like the trade, then break the workstation and set it again.
3. Repeat steps 1-2 until the villager has a trade you want to keep.
4. Buy/sell from the villager to lock the trades.

Work-around for chunk loading:
Use solid blocks to build walls along all the chunk borders (0, 16, 32, 48, etc) and use gates to keep mobs from moving between chunks. (Note: villager AI can get "stuck" on fences and open trap doors, but seem to know better than to get stuck on a gate.)

Expected behavior:
Certain mobs should despawn when you move away from them. Specifically, to keep a mob from despawning, you should do one of the following:
1. Feed
2. Tame
3. Trade (villagers only)
4. Name tag

Hello Shannon, you're right. These reports from people would really helpful for developers. People must mentioned how entities are despawned as you said.

My entities are despawning because my entities are located in two or more chunks before the game crashes. I built my fences around in one chunk after my entities are despawned more than one time, not any problem happened after I did that. Also doesn't matter entities are named/unnamed, they are still despawning if these entities are located in two or more chunks before the game crashes. I hope this comment would helpful for developers.

Hello Shannon, I will give you some information about this:

1. Version: 1.16.1 hotfix.
2. Platform: Android 9.0.
3. Entity that is disappearing: Villagers.
4. Coordinates where it disappears: There is a photo of the coordinates of my world linked in the publication.
5. Can the entity move: Yes, Villager can move through solid blocks, it has a bed and a lectern as well and a space to move.
6. Did the world crash: No, it is very rare for the game to crash.
7. Did you go to the Nether: Yes, but long before going to the Nether the villagers disappeared. So it's probably not the Nether's fault.
8. Do you interact with the entity: Yes, I trade with him. I also name him, but he still disappears. so it's the fault of the borders of chunks
9. Did you "save and exit" or just turn off your device: I always save the world, never turn it off before.
10. Did you move away from the entity and then return (unload the piece): Yes, I do that sometimes.

migrated 2020-07-01T03:33:31Z

In case its of interest:
1. Version: 1.16.0
2. Platform: Realm with players on Switch, Windows, iPad, Xbox
3. Entities that disappeared: Villagers, foxes, wolves, sheep, and doors
4. Coordinates: All over the world, different bases - all reported instances have been in an area where the entity can cross a chunk border.
5. Can it move: Yes, except for the doors.
6. Did the world crash: Often, we have been booted from the server several times.
7. Did you go to the nether: Often. 🙂
8. Did we interact with the entity: Yes, tagged, traded, tamed, sheared, etc.
9. Did you "save and exit": No, members of the realm are now warned that this might be a cause.
10. Did you unload the chunk? Yes

Note: In our case, we have changed the layout of farms and villages - putting up walls to restrict movement to within a single chunk - and have not had any further instances. I started with more visually pleasing fences and still had villagers despawn. Not until I put up solid blocks did the problem appear to go away. (fingers crossed)

Olá Shannon. É realmente muito decepcionante aumentar o nível de um morador para perdê-lo mais tarde, ainda mais quando escolhemos a troca que tanto desejávamos. na tentativa de ajudar, darei algumas informações.

1. Em qual versão você está jogando.
Percebi o problema em 1.14, mas atualmente jogo em 1.16.1 e ele permanece.
2. Qual plataforma.
Android 10.
3. Tipo de entidade.
Vi várias entidades desaparecerem, entre elas os aldeões, burros selados, cavalos, gatos e portas (esta última não tenho certeza se desapareceu devido a esse erro ou se foram quebradas por zumbis).
4. Coordenadas da entidade
Esse problema ocorreu em várias partes do mapa, mas, usando um programa externo, percebi que as entidades que desapareciam estavam presas entre dois pedaços; ou a área que poderia se mover cobriu o limite de dois ou mais pedaços. Há um aldeão no meu mundo que nunca desapareceu, percebi que ele está estático em um único quarteirão no centro de um pedaço.
5. Se a entidade puder se mover, de que é feito o curral?
As entidades que poderiam se mover e as entidades presas em um único bloco desapareceram. Ambos estavam em blocos sólidos, alguns com cercas ao redor, outros com paredes sólidas, outros ainda em casas com pequenas janelas de vidro.
6. O mundo caiu?
Não
7. Você foi ao nether?
Sim, mas às vezes a entidade desaparecia sem eu entrar no éter. (pelo menos quando notei seu desaparecimento, não havia entrado no nether há dias)
8. Se a entidade é uma multidão, você interage com ela de uma maneira que faça com que ela não desapareça?
Entre os que desapareceram estavam os aldeões com crachás, aldeões sem crachás, mas com os quais eu negociava, animais que eu alimentava, animais com selas e gravatas.
9. Você "salvou e saiu" ou acabou de desligar o dispositivo?
sempre "Salvar e sair".
10. Você se afastou da entidade e depois voltou?
Sim, eu já me afastei das entidades que desapareceram. Mas alguns desapareceram mesmo quando ele estava perto.

Eu realmente espero que esse bug seja resolvido. É decepcionante progredir no jogo, encontrando um raro encantamento ou equipamento de diamante em uma troca e perdendo-os imediatamente. Ou construa uma vila artificial onde os moradores não possam viver sem desaparecer.

There is a villager in my world who has never disappeared, realizing that he is static in a single block in the center of a piece.
5. Can you move, what is it made of or corral?
Entities that can move and how entities are trapped in a single missing block. Both were in isolated blocks, some with fences around them, others with dry walls, others still in houses with small glass windows.
6. Did the world fall?
No
7. Did you go to the other side?
Yes, but sometimes the entity disappears without me entering the ether. (at least when you notice his disappearance, he hadn't entered the nether in days)
8. If an entity is a crowd, do you interact with it in a way that keeps it from disappearing?
Among those that disappeared were food with meat, meat without fish, but with which I traded, animals I fed, animals with saddles and ties.
9. Did you "save and exit" or did you just turn off the device?
always "Save and exit".
10. Did you leave the entity and then return?
Yes, I'm already enjoying the entities that disappeared. But some disappeared even when he was close.

I really hope that this bug will be resolved. It is disappointing to progress through the game, finding a rare enchantment or diamond equipment in an exchange and losing them. Or build an artificial village where residents cannot live without disappearing.

As of 1.16.1 on Bedrock I randomly have hopper minecarts disappearing. They are completely encased so no mob can even touch them and yet they randomly disappear. Thus preventing my farms from collecting the goods. Not only is it a big loss of crops but I am blasting through my Iron to replace them multiple times a day. I really don't want to go back to farming everything manually as I have way to much to do in my world and can't be bothered by manually collecting crops all day when there is a clear automatic option.

Joshua, do your mine carts cross chunk borders? Chunk borders are places where the coordinates, when divided by 16, are a round number. 0,16,32,48, etc. I have found that editing my builds to block entities from being on a chunk border has stopped the random despawning. In every instance where something has despawned (when it shouldn't), it was possible for the entity to move between chunks.

For example, in the attached images, I have built walls along the chunk borders and use gates to keep the villagers from being able to move between chunks. I have holes in the walls to allow 1 block high entities (chickens, cats, and children) to move between the chunks, but not the adults. This is a village that I started early-game from two igloo villagers, which is why it is underground. I also modified my minecart automatic farming where I use moving minecarts to not cross a border. The build I am showing does include minecarts that are on a border (to allow the farmer to throw carrots at the other villagers), but those are locked into a single block and cannot move.

If you want to collect from multiple chunks into a central location, I would recommend looking into using water/packed ice/bubble elevators/droppers and/or hoppers to move stuff across borders.

All villagers in my game have despawned. Never had this issue before the Nether update. Running PS4 2.09 updated this morning for the login screen issue. Like so many other posters, villagers are in a safe, enclosed area with ample light, beds, food, and crafting stations. Despawns have happened in conjunction with raids, when returning from being out of chunk, and when we've been in the chunk but slept. Last villager died as a result of the many game crashes that now plague split screen play.

Replying to Shannon's previous comment, yes my pumpkin smasher sits between to chunks with two hopper Minecarts going between both chunks for collection. I think it's important to mention that they don't always disappear, just randomly and after more testing it seems to only happen when returning to the overworld from the nether

Lance, Can your villagers cross chunk borders? As you can see from previous comments, this seems to be the defining characteristic of this issue and the work-around for not having entities despawn. If you have an example that contradicts that assumption, then that is very useful to know.

Note: fences along chunk borders can allow entities to cross a border b/c they can move into the neighboring chunk and get stuck on the fence. Only walls will completely block the villagers.

That's not what this is about
The issue is this started happening AFTER the nether update

So it seems this prob is an issue with the update
I have never ever had a villager dissapear for a year on this world, until nether update
First 1 then 3 then 4 then 7
Just had my horses and donkeys dissapear from a fenced in paddock

Even though it is technically simple to avoid this problem, I still find it very bad to download a texture to be careful not to place the Villagers on the borders. But when I see this bug it must be very difficult to be corrected for the time that it has existed until now no correction. But I think that this bug must be complicated to solve, considering the date that this bug report was created.

@ Kurt, Hi.

If you read the bug description, there is a message from Mojang that states in part: "Currently entities can end up being lost if they happen to be positioned on the boundary between two chunks when the game crashes." In other words, that is exactly what this issue is about.

In your original bug report that you opened yesterday MCPE-90596, you asked for help. Those of us who are asking about entities crossing chunk borders and suggesting work-arounds are trying to to do just that - help.

I get that you are frustrated. It helps my 10 year old and his friends to think of this bug as a creeper. While it is really frustrating when a creeper blows up your chicken farm, it is a part of the game. We practice our elocution and then rebuild - this time with a moat and a fence. ¯_(ツ)_/¯

Please do not leave comments that offer nothing but complaints and insults. It isn't helpful to either the developers or the community. There is enough stress in the world right now and Minecraft is suppose to be fun.

Peace.

migrated 2020-07-10T02:31:55Z

I totally agree with you @shannon !! But I hope that the developers will find a solution to solve this bug and not be like a creeper (which will be part of the game forever). ;-;

migrated 2020-07-10T05:25:18Z

I second @shannon as well. As @kurt said, Minecraft is not designed to be played in one chunk. I think everyone can agree on it. However, although it may not seem like a graphically demanding game, its codebase is based on the old pocket edition, so it is not without its flaws.

The reason chunk boundaries are such a problem are because the worlds are stored by the game according to their chunks. When the world is saving, the device can only do so much at a time, so it saves chunks, or possibly groups of chunks/regions in a sequence, as it cannot capture the whole world in one instant. So let's say its order is A then B then C. We will assume for this example that the villager/minecart/horse/dog/whatever is in chunk B. The game saves chunk A and in the instant before chunk B gets saved, the entity moves into chunk A, which the game assumes had already been accounted for. By the time B is saved, the entity is fully into the previously saved chunk. By the time the game finishes saving B, C, etc, there is a possibility that several entities have wandered into chunks where the game did not properly save them.

As shown by the Affected Versions list, this problem is nothing new, however something in the 1.16 update has amplified the frequency with which it occurs. There are many bugs relating to entities and redstone on chunk boundaries. The best we can do it spread the word and hope Mojang finds a solution.

Per https://minecraft.gamepedia.com/Minecart_with_Hopper ,"A minecart with hopper can travel more than 85 blocks without stopping (as opposed to a normal cart going less than 12 blocks) from a dead stop using a 2 powered track starter even with another cart in front of them." So I do not see how telling people to put up a wall every 16 steps is anything short of absurd. This is not a feature of the game, but clearly a bug.

Yet I had a creeper stuck in a boat and he despawned a couple minecraft days later. I also had a pig stuck in a hole and he despawned the next day. I hope they fix this, it's frustrating. And I definitely don't want this to be a permanent feature.

@ Y F

Hi. What you are describing sounds like it might be intended behavior. With 1.16, Bedrock despawn rules were intentionally changed to have parity with the Java edition. This means that only entities with which you have "interacted" will not eventually despawn once you are 32 blocks away from the entity. What counts as an interaction is a bit vague, but definitely includes name tags, leashing, feeding, and taming.

That said, there is also a bug right now where any entity that is either standing on or can cross a "chunk border" can also despawn, even if it has been interacted with. That behavior is super annoying and definitely a bug.

Shannon Young points out an interesting separate-but-related potential unintended consequence of the change in despawn rules: villagers you have not interacted with will despawn when you travel more than 32 blocks from the village. I was wondering why, each time I returned to a village, I would find vast numbers of baby villagers, when I had not altered the number of beds, and a raid could obviously not have happened while I was that far away. A few interesting consequences might be worth watching:

+what happens to the user reputation when this happens? Does it increase at a vast rate because of the introduce-a-new-villager reward, despite the user having done nothing except leave and return?

+what happens if the farmers of the villagers are the ones that despawn? Does the lack of farmers, and thus food, mean that villagers can't breed to replace the despawned villagers? This could be an inadvertent way to quickly turn a populated village into an abandoned village.

+what happens if the user visits and departs a village several times in quick succession? Does a group of villagers despawn each time, again providing an inadvertent way to turn a populated village into an abandoned village?

I know this issue of entities disappearing along border chunks is a knotty problem, with years of effort trying to isolate and resolve it, so if this villager despawn issue should be a separate report, let me know and I'll repost this as a separate item.

This is happening to me consistently in my village that seems to span multiple chunks. I blockaded the villagers in their homes while I secured the village, and they stayed alive as long as they were secured within their homes. They were like this for several dozen in-game days, multiple app exits and closures - sometimes with me working through the night, and sometimes with me sleeping in random beds throughout the village.

Yesterday I finally released a few of the villages to wander, I saw three of them breed two children. I remained in the chunk, or the one to the left of it, working on my farm for a few in-game days. When I re-entered the village, all but one of the wandering villagers had disappeared without a trace. No zombies had arrived, and there were no long falls for them to suicide. Perplexed, I further secured the village and released one more villager from his home.

Two in-game days later the original villager (with whom I had traded and should therefore be locked) had disappeared. Today, all villagers are gone except the one still secured in his home. I regret not leaving two so that I could breed them.

What I think is happening is that my village spans the edge of two different L2 maps, which I assume means that it spans multiple chunks. The village bell is in the eastern L2 map, but the villager's bed and work site were both in the western L2 map. I was hanging out in the western L2 map when the villager disappeared. I believe that he had visited the village bell for his usual afternoon socializing, but despawned when he left the map I occupied.

All of this happened on my iphone 7 game, on version 1.16.1. I did exit the app a few times during that play session, so that might also contribute.

I'll also add that there's a several-block elevation difference between parts of the village near the village bell. In addition, the villagers had to go up, and then back down, 2-5 blocks to reach the bell for the daily social time. They seemed to have difficulty navigating that elevation difference, and it wouldn't surprise me if there was a bug somewhere in the pathfinding.

I have a large village that spans multiple chunks, with several houses on chunk borders. If I let my villagers wander around, they disappear consistently. I've lost about a dozen. After remodeling several houses so that they're no longer on chunk borders, as well as locking villagers into the houses so that they can't get more than a few blocks from their bed, and none of them can even set foot onto a chunk border, I haven't had a single disappearance in over a week. Some are named, some are not. Seems to confirm that it's related to chunk borders, and possibly also to how far villagers are able to wander from their beds.

Edit: Bedrock realm I play on Windows 10 and Switch

My experience if it helps: Bedrock on Xbox One, I have a rather dysfunctional raid farm. The activation area to get Bad Omen (uses trident killer) is too far from the kill platform (where a single villager is encased) to trigger a raid so I have to go down to get Bad Omen then up to trigger the raid, rinse and repeat. Recently I traveled to the farm for the first time since the 1.16 update. I turned trident killer on, got Bad Omen then ascended to the kill platform. The raid proceeded normally (normal level) through all five stages and I got the preferential trade icon (emerald symbol). I went down again and successfully picked up another Bad Omen and then back up. As soon as I was in range the first raid stage began charging but my emerald emblem began to flash at the same time. The first raid stage never finished charging. Both the raid bar and the emerald symbol vanished at the same time. I pillared up to the villager compartment and chopped into it. He was missing.

I was directed here by a previous helper for reporting the same thing so I thought I would input my experience to help. Our realm has seen mostly horses and villagers (all with nametags and fully interacted with) disappear quite randomly. Also, a fox which was bred by another player. I haven't yet checked if these are next to chunk edges, I'll look into it and update this comment. It is important to note that two horses were very close together in one pen when they vanished which works with the chunk boundary issue but then on the flip side a single villager locked in a house with other villagers in a completely fenced-off area disappeared which seems odd with the current chunk boundary problem suggestion.

@GoldenHelmet Nope, they are just sleeping in bed normally (I attached a new pic to show this). Yes, the villager who disappeared was the most recent one added. Does that make a difference?

I initially built this village to let them roam free–it's fully lit and has a massive wall around it, no chance to mobs to get in. Bell in the town square where they would all gather during the day, then they'd return to their respective houses and beds at night. That worked fine for a few in-game days, but it wasn't long before over 10 despawned all at once. Some had been cured from zombies, others had been bred. Some were named, others were not. Some had been traded with, others hadn't. Obviously they were all crossing multiple chunk borders daily, as I didn't know at the time about this issue. Since remodeling the houses to not sit on chunk borders, and using fences to confine them to the area immediately around their beds and job blocks, I've managed to prevent any more despawns, until now. I currently am back up to five librarians, two farmers, a cleric, and a fisher, all cured from zombies, some named, all traded with, and this latest librarian (who would have been number 6, and the fifth living in this specific chunk) is the only one to despawn since I made the changes to the village.

Edit: Worth noting, that's actually a different chunk–the fence is a chunk border. So that villager was the only villager in that chunk.

I reported on this while back. My villagers were dissapeared on my villager hall. As I think it was due to them walking across chunk borders at time of saving. So far, all I have done is move workstations and beds at lest 3 blocks away from the chunk borders. Since I have done this, I have not had any issues with my game crashing or losing villagers.

@unblocked this is obviously a very difficult bug to work out and fix. Complaining that they havent fixed it yet doesn't help or add anything that could help them to fix the issue.

@goldenhelmet Been adding villagers around the village for a few days now with no incident for some time. However, just had two more librarians disappear from the same side of the same room as the last one. Once again, they have no access to a chunk border. This is on Switch on a realm. I never entered the nether during this time. However, i always use the “save and quit” option. Notable: these were NOT the most recent villagers cured and homed. I have a cartographer and an armorer who are newer and still present. Pretty bummed, as i thought moving them off borders had helped. Seems to be a problem with this specific location within the village. I’ll post a screenshot when I’m back at my pc tomorrow. One of them had fortune AND mending books😞

edit: should mention as well that both new disappearances were nametagged.

Same issues on my realm. One player keeps losing animals from her farm, another keeps losing villagers that are diamond level and I keep losing hopper minecarts. We are all very frustrated.
Please fix this fast! I have subscribed to realms for years and when you add it up, we spend good money on this feature (not to mention owning Minecraft on 6 different devices and the money my son always begs to spend on mine coins).
My point is, this bug is HUGE. It’s having a big impact on game play. Repositioning everything around chunk borders simply isn’t a solution when our world is built up and huge farms that we have dumped hours upon hours into can’t function properly and one farm can’t be moved without moving a dozen others first.

So far I have lost 4 horses which I had kept in a stable. All of them had a horse armor and were saddled. Losing such valuable items is really painful. One thing I noticed that my stable intersects four chunk border, which could be the reason why my horses disappear because when the game crashes, they might have stood between two chunks.

This issue needs fixing immediately! I can't loose any more horses 😢

I have been dealing with disappearing villagers for a while now. but with the iron farm buff in the last update, the losses are starting to stack beyond what is acceptable. these villagers have a bed, a workstation, cannot move from their position, have been interacting with, are upgraded to at least level one and ARE NAMED with nametags. there is literally nothing else I can do and they are still disappearing.

I've uploaded three screenshots (library1, library2, and library3). There's a chunk border down the middle of the building (right on the line between the bookshelves and the fence, so the villagers can't possibly touch the border). The librarians on the left (east) side have been there for weeks without despawning. Any villagers I house on the right (west) side despawn within a few in-game days. This is fairly consistent–3 villagers have despawned from that side of the room. They can't access any chunk borders and no enemies have spawned inside. I've added villagers to various other houses throughout the village (9 in total), and none have despawned in some time. For whatever reason, this seems to be a problem with this side of this house specifically.

migrated 2020-08-11T07:17:03Z

On my friend's realm, I like to keep a horse tied on a fence post next to my house with a name tag on it, but after a while it seems to despawn, so I have to replace it. This has happened multiple times, and I believe it has been happening since about a year ago, before the nether update. It doesn't seem to be consistent; sometimes it happens after hours, sometimes after days, sometimes to horses i ride often, sometimes to ones i rarely use.

I also had a named horse hanging above the ground on a leash near my house for months. Yesterday I took it down and left it on the ground tied to a fence. I also tied a new named horse next to my house. Today I checked and it the horse that used to be hanging is gone, while the one that I recently tied next to my house is still there.

I know they are despawning and not dying from something because there is never a death message and the lead can still be seen tied on the fence post. I tested to make sure, and found that when animals die the leash consistently properly disappears and drops as an item.

My friends have named horses that are fenced up and don't seem to have this problem.

I also have a horse, a donkey, a mule, and a skeleton horse tied to a fence post underground below my house (All of which I never ride) and they have been just fine as well.

We also have 3 skeleton horses tied up in the area, and they seem to be fine, although I think there used to be 4 a few months ago.

Not sure if this is related, but I also in that realm yesterday, I pushed my horse through a nether portal into the overworld, killed a ghast, then went through myself. When I came up in the overworld, it was gone. At some point I quit the game and came back, and at some point i went back in the nether, but I don't remember which was first. The next time i returnd to the overworld, the horse was back.

@GoldenHelmet I've had the exact same thing as Rogue Cheddar happen in a peaceful world, with no hostel mobs, so it's definitely not a light issue. I have all my Villager locked up now, so they can't move around. Seems to help. But I had a horse tied on a leash, same thing happened in peaceful, horse disappeared, leaving the lead tied. I've had bees disappear to. Whole nests empty. Based on my experience with testing it. It's definitely got something to do with loaded chunks, and mobs coming in and out of those loaded chunks. Or with loading from a save or nether portal. Confined mobs rarely despawn.

migrated 2020-08-14T17:07:34Z

Interesting about the light levels, how did you produce those numbers? The fourth wall in that room (the one not pictured) also has several torches on it, so I don't see how the levels can actually be that low. I will add more torches to the middle of the room--however, I really don't think that's it. I visit the room often to check on the librarians, and I've never once in many weeks of playing seen a mob spawned inside. And this is on normal difficulty, so, as you say, odds are some of them would have turned back into zombie villagers. None have.

Regarding your other questions, I typically head to my bedroom to log out. It's roughly 2-3 chunks away. And my Nether portal is nearby, about the same distance away as well. Would an exact block count help? I don't have access to coordinates on this realm.

In any case, I haven't had any more despawns in the past week plus, besides sheep. (I have left that side of the library empty. Sheep constantly despawn, though. I have to continuously breed them just to keep the population up.)

Edit: It occurred to me that the last batch of despawns happened when I was playing in the realm on my Switch. I have played exclusively on PC since then and have had no despawns (again, besides sheep). Maybe that has something to do with it? Could the platform you're playing on affect the bug? (for all previous despawns, I'm not sure whether they were all on Switch, or some on PC, as I usually switch between the two frequently.)

migrated 2020-08-14T19:10:19Z

Interesting idea concerning other mobs being able to move between borders.

In our current realm world, I have not had any villagers despawn (knock on wood). It's set up so that no mobs - passive or hostile can spawn inside the village borders. My sheep, however, keep despawning and my son's farm animals keep despawning, but the fence areas do allow for other mobs that are naturally spawning to move in and out of the chunks. In the village, the only mobs that could spawn in the village and then move out of the village are fish and drown.

In the previous realm, there were chickens, rabbits, cats, and foxes that could move freely throughout the several chunks of the village. These would sometimes despawn (as per the original bug description), but the strange thing was that the villagers would also despawn. Always the same two villagers, neither of which had their bed or work station anywhere near a border. This was a tundra village that was underground so its not zombies and I never came upon an illager patrol that spawned in the village (after the 1.16 update).

Brian 2020-08-18T00:27:14Z

I have been playing the same map for 18 months. This issue started happening to me ONLY after 1.16.2 update the other day.

I had an entire village at my base with many diamond level villagers and all but a literal handful have now poofed for no reason. Most of the villagers remaining are unnamed nitwits. No other named mobs such as horses or donkeys have despawned.

Uncountable number of gameplay hours leveling villagers up have now been lost.

migrated 2020-08-22T01:00:45Z

I have just started experiencing this issue on a realm we just created. In the past 3 days I have had two foxes, two dolphins, and 6 sheep despawn, all with name tags. My base is located on a chunk border so I'm really concerned I'm going to lose all my animals, and it's not like I can tell the whole server to not play the game. This is really concerning and annoying, please fix this bug ASAP. Some of my animals that are name tagged are really rare (ex. Skeleton Horse).

GoldenHelmet 2020-08-23T22:10:08Z

@@unknown How did I calculate the numbers? Just by counting blocks from the torches on the wall. How did I put them in the picture? I opened the picture in MSPaint, cropped it, typed the numbers on it, and saved.

As far as your platform, I think the device would only make a difference insofar as different devices have different processing power and save/load times, and that could impact how reliable the saving and loading is. There are several bugs that depend on slow loading (MCPE-31389, MCPE-74333, etc.) that I can reproduce by bogging down my PC.

However, the fact that you had a lot of despawn problems on your realm and none while playing locally may point to another issue. A lot of the comments on this ticket relate to realms worlds. According to MCPE-92017, realms actually continue running while no one is logged in. It seems to me that could be a huge source of the random despawns. If the "save and quit" process does not work the same on realms as it does on local worlds, perhaps it is more like crashing?

@graham Bourke.... If you divide your coordinates by 16, and get a number with no decimal, you are on a chunk border.or you can use chunkbase and find your coords and it will show you if you are on a border(seed does not matter as chunk borders are the same for all worlds).

migrated 2020-08-26T19:09:53Z

@graham Bourke - for clarification, if the coordinates are divisible by 16 those would be the northern or westernmost block of the chunk. As an example 32, 68, 64 to 47, 68, 79 would encompass a chunk with the first coordinate being the northwest corner. I used to have issues with everything despawning but now I start every build that includes villagers, mobs, or minecarts by placing blocks on those borders to make sure nothing will cross into another chunk and haven't lost anything since.

Me too, chiming in.

I'm trying to create a living underground base in a survival bedrock realm, on Windows and Xbox. Version 1.16+ and still happening.

I have lost many horses, saddles and leads with mysterious horse despawning.

My "Stables is a roughly 10x10x7 area mined out of the side of a mountain, with a 3 block wall (that I manually mine through if I do ever want to set foot [shudder] outside), there's a fence pole somewhere near the back (inner) side of the mountain that I tie my horses too to stop them going too near the outer edge wall.

[media]

The 2 key things here is I am able to recreate fairly regularly (Play for a few hours over a few days and my horse will eventually warp away), on both the online realm and within a local copy of the world. One other detail is that (not sure, didn't see mentioned above but its a bit TLDR up there!) in my case the lead is still attached to the fence pole, in that the binding around the fence pole is still present and I can hit it to break the lead (the lead item drop disappears, I assume appearing near the horse), however there is no "lead" proper connecting said binding to the horse, and of course no horse.....

It really feels like the horse has spawned somewhere weird, and ONCE after breaking the lead I did eventually find my horse. about 50 blocks away. All my horses are name tagged. (I hope this bug is fixed quickly coz I'm quickly running out of horse puns to name them with at this rate! lol)

I don't travel to the nether or end, there is not even an active portal within 10000 blocks. My base is a sprawling underground network so I am working alot of the time between 4 and 50 chunks away from where the horse is and will regularly walk as close as 1 chunk pottering around. As mentioned above feels like as I move about in the base I might be loading and unloading the horse chunk naturally.

I have not yet identified the chunk alignment however, as its a vanilla survival realm and the players are all really on point about suspected "cheating" so I've held fast and not even allowed coords to date. I will download the realm and do some chunk alignment and get back to you.

Note: I also have 2 villagers in a boat that I plan to use to breed and build a trading hall and iron farm in my underground complex, they have never despawned and are NOT nametagged, however they can not move out the boat and thus are effectively contained within a largely unused chunk.

Edit 1 : Currently tested to 1.16.2, just got the note loading in that 1.16.4 update is incoming on the realm.

Edit 2 : I didn't mention but all my observations above are running in my vanilla Realms server, no crashes, no updates (at time of observation), or a copy of the world that I've locally downloaded. @Shannon Young below gives me the idea of downloading a copy of the world (since report updated to 1.16.4) and inspecting my base chunks with MCCToolchest, any additional findings will be posted!

And when i did a bit of work on my project, the farmer and child has disappeared/despawned. This is super annoying because it took me 3 hours just to get both villagers 600 blocks to my house. And im pretty sure the village i took them from has no more villagers. So now that there's no villages near my house at all, how can i get villagers without cheating?

I have had a similar experience to Danny a few comments up where he says

It really feels like the horse has spawned somewhere weird, and ONCE after breaking the lead I did eventually find my horse. about 50 blocks away.

I once found a missing villager in a cave about 50 or so blocks outside of my fully fenced-in village. Other than random teleport, the only conceivable explanation is that I left a gate open during a raid and he wandered out (despite villagers seeking shelter during raids) onto the trapdoor that goes over the moat, jumped down, went down a 7-block high hill, across a river, up 6 or so blocks on the other side, and continued along the coast for a while--all heading southeast away from the village (against the NW wandering bias, MCPE-41092). So I think part of the cause behind this ticket could be a bug corrupts mobs' position data during saving/loading.

Villagers went missing from a single-chunk village (iron golem farm) where the villagers are constrained to a single x,z position and standing in water. The village was built over water to guard against "land" mobs spawning in the village and then leaving the chunk. Using MCCToolchest to check the number of villagers assigned to the village, there should be 20 villagers but there are only 13 so it isn't that the villager teleported. Instead, I can confirm that they despawned.

I have lost countless cured zombie villagers to this, which makes the bug all the more frustrating because of the resource costs. This happens during the course of normal gameplay as well, with no crashes occurring, and with villagers contained within a single chunk. Leads me to believe that if it is chunk related, travel through nether portals results in some chunks just not saving, or else some chunks fail to save during standard game closure.

migrated 2020-09-21T14:07:17Z

I promised to report back in after checking the chunk alignment of my underground horse pen...

I think I see a problem and it validates a chunk save/unload/load issue. I got the chunk alignment very wrong! by my reckoning thats 3 other chunks the horse can reach while bound to the lead and post. 1 West, 1 South West and one South (FYI, in case orientation is relevant).

I stress however that this occurs on normal Realms server, which is producing backups and seems to be saving when players log out. There's no sign of a crashed save and of course you can't force shutdown a realms server, just the client.

My situation is repeatable (as above), I've rerun it in 1.16.4 with a new lead attached horse (no nametag, I've run out) on the Realms server and reproduced the old "despawning horse, no lead" trick...

I will realign this with the chunk, and repeat the experiment!

migrated 2020-09-22T11:33:03Z

This 100% is a chunk border issue. I have had nametagged mobs despawn before on chunk borders but never inside the chunk/away from the chunk borders. Easiest way to reproduce is to attempt to crash the game, but this can happen by simply closing it, though closing it makes it less likely. From digging into the coding this appears to be the mobs sometimes failing to save to the chunk between 2 chunks, though it's not 100% of the time that they disappear. I would estimate every 1-30 times before vanishing. Hope this info can help someone.

In fact unless someones portalled up from the nether (unlikely but possible) for some reason near my base (I've seen no evidence of building or even a tunnelling out or portal in about a 2 or 3 thousand block radius in all my local exploring) Id say the nearest "known" portal is about 20,000 blocks away, near the world spawn.

I do log off in the base, I have a minecart hopper that goes over a chunk line (needs rebuild, this is covered in MCPE-16863 ) so I find if I stand next to it so both the chunks it spans are loaded this is the best place to log off to ensure when after some undermined time the realm saves it saves both those chunks and I don't keep lossing my hopperCarts.
This is about (guesstimate) 70 to 90 blocks away on the Z (north), perhaps 15 on the X (east) and about 8 to 10 down on Y. I do not tend to AFK much in the base (or at all) as I spend my time waiting for machines building the base and excavating the mountain.
Hope it helps. The sim distance is set to the default as I play on Xbox mainly so whats that 4 chunks? Not sure if my horse container is close to the sim distance boundry, perhaps the horse is wandering out of the post chunk and into/out of the sim distance as well as the chunk, not sure.

Please mention me back if you want me to measure precisely.... I do hope it helps!

Also @@unknown you might wanna check out MCPE-16863as it pertains specifically to minecarts and variants disappearing, this one is more about named and interactive entities like villagers and horses.... :thumbsup:

I experienced a similar issue with "chunk cloning" using structure blocks. If you don't know what I mean by "chunk cloning", it's copying all the blocks and entities from one chunk to another, using methods such as combinations of commands (such as /clone and /summon) or in my case, structure blocks. (if requested, this will be moved to a separate report)

VIDEO EVIDENCE

I’ve made a video systematically reproducing this bug on my Windows 10 PC on a local world - please do take the trouble to watch all 16 mins of it at https://gofile.io/d/s14lrl [New link : https://gofile.io/d/A0hGrx or https://drive.google.com/file/d/1haCHRTl9YCLKbYW0T2c6komcck82hDKY/view?usp=sharing (I couldn’t attach it directly here since the file size was too large) and read this long comment if you think you might also be experiencing this bug and want to know more - I’ve written everything I know. (Or watch from 4:00 to 8:00 if you want to see the problem and don’t have much time)

MY EXPERIENCE :

I've been experiencing this bug since 1.12 or so (that was when I first noticed it) - mainly due to crashes - minecraft on my PC (not specialised for gaming etc, a regular desktop computer running Windows 10 Home 64-bit with 8 GB RAM, no external GPU and an Intel i5 3.2GHz processor) crashes very frequently (or it used to - the 1.16.x updates have fixed many of these crashes). It has caused me lots of trouble and wasted hours of effort in my survival worlds too.

In the video, I've tried to make the game crash by itself again, as well as forcibly crashing it later on. From the discussion above, I gathered that nether portal usage and travelling far away in the overworld are also possible causes, though I hadn't really noticed the effect of these while playing ; and I coudn't reproduce it this way in the video as well. (Possibly these are causes only on realms ? Or do nether portals need to be in specific places relative to the entities and chunk borders ?) Anyhow, I'll try to list down everything within my awareness about this issue to reduce ambiguity and help pin it down.

So here are my personal observations (I've lost 100s of entities in survival repeatedly over the years due to this bug; so I can say everything below with confidence as I've seen each of these effects several times) :

SOME FACTS :

IMPORTANT Any entity that crosses over a chunk boundary into other chunks is at risk of disappearing due to this bug. Entities that don't/can't move between chunks ~~are 100% safe and will not disappear~~ shouldn't disappear as long as another entity with persistence doesn't enter the same chunk as well (not sure about this). (For this reason, mobs that move around more, such as villagers, bees and chickens seem to vanish more frequently than those that don't, like armour stands or turtles on land).
IMPORTANT The absolute distance of an entity from the surrounding chunk boundaries doesn't affect anything - all that matters is whether it has crossed into other chunks recently (I've seen villagers standing in the middle of a chunk vanish while others standing on a chunk boundary remain...) ('recently' means before you last normally 'Save & Quit' exited your world)
A physical boundary around chunk borders is actually not necessary for entities that won't walk around, like tamed wolves/cats/parrots that are sitting down - they won't despawn; but it's probably the only way to keep all other mobs from wandering around, so better to use it.
For crashes, any form of crash (natural or forced) (any way of exiting the world or Minecraft app without normally saving and quitting) can cause this bug to occur
For villagers that disappear due to this bug, any workstation/bed the villager was linked to remains unclaimable by other villagers until you break and replace it (this was already noticed by @Nicholas Otto as well)
When villagers disappear, the population of the village seems to be affected immediately though, as reflected by subsequent iron golem spawning rates (after 1.16); and when you replace the bed, willing villagers with food do start breeding to occupy it again, as if the population was < 100%.
If the mob that vanishes was attached to a lead, the 'lead knot' remains on the fence post visually, but disappears without dropping anything when you right click on it (so effectively the lead (and any nametags/saddles/armor/etc) are lost along with it) - also shown in @Danny 's picture

A POSSIBLE MECHANISM :

This is certainly related to chunk boundaries and how entities/chunks are saved on bedrock edition.

I haven't personally ever seen @Brandon Paulk 's thought that the entities crossing chunk boundaries may be getting teleported to other parts of the world occur for myself so I can't say anything about that.

One mechanism suggested by @Blobs2 - quoting it again -

Suppose chuck A saves, a mob from chunk B comes to chunk A, chunk B saves, and the game crashes before chunk A saves again. Then both chunks would have been saved without the mob.
I think a similar occurrence could cause mobs to duplicate. Has anyone observed this?

seems very plausible, but I want to stress that it doesn't seem like entities ever duplicate (even if chunks are being saved according to a specific order, the way in which so many mobs walk around while not pathfiniding seems very random, so there surely would be instances where the mob was in chunk B to start with, got saved there, moved to A and got saved again; and the game crashed before B was saved without it; and it is duplicated on reloading those chunks). I haven't seen anything like this happen myself or heard of it from others - so the mechanism probably doesn't allow this ( @Jonathan Hanzel - i think duplicating mobs using structure blocks and /clone commands is intentional)

Hi @GravityBoots,

That’s a wonderfully extensive report! Thanks so much! You are incorrect, however, on one point.

Entities that cannot cross borders can despawn if there is a different entity that can cross. I’ve had this happen bc of chickens, tamed cats, tamed foxes, etc.

Note: it does appear that the entity that can move across borders must be an entity that the game rules say shouldn’t despawn when you move more than 44 blocks away from the entity. What that means is that you don’t need to guard against stray cats, for example, but you should ensure that if you tame a cat, that it cannot be pushed across a border when sitting. In fact, it is best to ensure that the cat is wholly out of the chunk once tamed and cannot cross back into it.

This despawning is occurring more frequently on my realm. I have had entire buildings of villagers with trades and leveled up disappear, named entities are disappearing as well for both villager and animals. I have had rare items like skeleton horses disappear. It also seems like the villagers have a hard time finding trades and can get locked into a trade while then stationing at another area. A farmer keeps going to a mason stone or a cleric to a compost bin. When they disappear it seems to upset the logic for the trade to the associated task and I have to go around and break all stations and then replace one at a time until the villagers are reset. This break in the linkage between the villager and their job seems to occur after a despawning event. Tried to stop using nether portals and it improved but happened again without nether travel.

migrated 2020-10-08T02:17:20Z

@Shannon Young - Thanks for pointing that out ! I've edited my comment to reflect that too...

I guess I hadn't noticed it since I had chunk-aligned all my farms and trading halls in my survival worlds and fenced off more or less everything that contained mobs with persistence (which are mostly in my farms), so nothing was really crossing over - and that appeared to be a failsafe workaround. I'll keep this in mind !

I'm curious though - does it have to be an entity of the same type (like a tame cat moving into a chunk with other tame cats, making them disappear) or any other kind of entity with persistence (villager, etc going into the chunk with cats) that can make this happen ?

@Gravity Boots

Thanks on behalf of the community for the write up,

Suppose chuck A saves, a mob from chunk B comes to chunk A, chunk B saves, and the game crashes before chunk A saves again. Then both chunks would have been saved without the mob.
I think a similar occurrence could cause mobs to duplicate. Has anyone observed this?

I too would agree with the actions in @Blob2' quote however the circumstance is incorrect. I have repeatedly demonstrated the bug on an Xbox started and based Realms server (I have loaded it on my Win10 machine to copy, debug, capture, ect), which is not crashing as the relevant world backup is created as I save and quit as last man on server.

It is absolutely not a crash, but is related to the saving procedure. I feel this is important because when debugging (I am a programmer) often the method to investigate effects of crashing or throwing exceptions is in a very different logical place to say in our problem here the saving and unloading of chunks during the state change (the instance of the game on the server unloading).

Of course forcing a crash gives us a better breakpoint and so will cause the effects more repeatedly,

I do wonder if its the order and time it takes to unload and save chunks that's the problem, i.e. for a simple example lets say the game saves blocks 1 to 9 in the order 1, 2, 3, 6, 9, 4, 7, 8, 5. Coz of the size of the world we're talking hundreds of loaded chunks and the fact entities are still moving (from 5 to 3 for example) while saving means there is a window of time between saving of 3 and 5, if you force a crash you see the result because 3 is saved after the entity left and the save is aborted before entity reenters 3, likewise in normal non crashy circumstances ("non crashy" is strong development terminology lol) if chunk 3 is saved but entity moves into 3 after saving before the game gets to 5 the same result of disappearing entity exists.

It also seems evidenced by the frequency of the reported instances above, a lot more report it happening on crash of a local game (as it forces the case) but less frequently (as chance of entity changing chunk mid save process is much reduced) in cases of normal saving/exiting behavior.

It would also serve as a conjecture as to why portals cause issues, in that again my realm the issue is reproducible and there's no portal behavior anywhere near, however I am affected by the issue on save not crash, so if portals cause some sort of crash or hard stop in the overworld saving there's your smoking gun once again.

(FYI, I also witnessed this is a village in the wild, fully populated one day and down to 3 villages the next, with plenty of workstations. It is situated about 4000 blocks north of base and 6000 blocks south of spawn, basically I stop off there on way back and forth)

@GravityBoots

No, a single tamed cat that can cross borders or is sitting on the line between two chunks, can cause villagers that are wholly encapsulated to despawn. This scenario happened to my iron farm. I set it up so it wouldn’t kill the cats for my daughter. She tamed them and left them sitting on the ground. I pushed the cat across the border (oops) and later realized that some villagers despawned. I then used MCCToolchest to look at positions both the cat and some of the villagers disappeared.

In a different world where I had set up a village that crossed several chunks, the villagers were restricted but bc my son liked to prank my base by throwing eggs and creating bunches of chickens, I put a name tagged fox in the village and made 1 block holes for the fox to go through so he could kill the chickens. Kept having villagers despawn in that village, too. It took a while to figure out but someone has observed that there seems to be a connection between despawning entities and other entities that cross a border.

Anyhow, its a weird edge case but now I build solid walls along the borders of my villages which are all 1 chunk with < 20 beds. That way, no golem spawn and the entire village loads/unloads at the same time. Haven’t had problems since. (Fingers crossed)

I'm not sure if this is related and if not, I'm glad to open a new ticket, but we've been having issues with parrots disappearing on our server as well as traded and locked villagers loosing their trades and attaching to random work stations.

With the parrot issue, I and other players travel through their portals into the nether while their parrots are sitting in their bases. The parrot or parrots (sometimes multiple) then appear on the players shoulder after they've crossed into the Nether. When this happened to me, I was unable to remove the parrot at my portal in order to send it back through so I sat it down and went into our spawn portal. When I came back my parrot was gone, and oddly, so was my parrot that was still at my base. (My base mate's parrots were still there but were no longer sitting and were flying around.) The same issue happens with other players although in some instances, when those players have found their parrots in the Nether, they have taken them off their shoulder and let them fly through the portal while they walk through, at which time the parrots disappear. Often those parrots reappear minutes, hours or days later at the players base. (My parrots have never reappeared. It's been over a week)

Regarding the villager issue: My base mate accidently brought the bad omen to our base. After defeating the raid I went to trade with my villagers and noticed my Unbreaking III villager was now a fishermen. I thought maybe it had died during the raid and the village had spawned a fresh villager who just grew up fast...lol I reset him back to an Unbreaking III and traded with him. A few days later I went back to trade again and he was once again a fishermen. Furthermore, another villager had also lost it's trades and was also a fishermen.

Hey @Yaya,

Welcome to the thread/epic. Your comments regarding your villager despawning during the accidental raid might be relevant, sounds like during the raid you had entities moving over the chunk boundaries so might be a cause for despawning.

Regarding parrot despawning, ~~I'd suggest adding your comments to this ticket :~~ MC-201384

Regarding Villager trade binding, I'll edit with a link to any issue I find however this is also a long running and separate issue so I'd bet my hat there's an opened (reopened) issue or 3 on here! 😃

This may be one of the causes of the disappearance of villagers, but on my map they despawn at the borders of chunk randomly

migrated 2020-10-14T20:55:25Z

Been messing around with this on a Bedrock Xbox Realm. What I've experienced is twofold. One; entering and leaving any Nether portal can cause named entities to despawn. I traveled several 1000s of blocks to enter and leave the Nether while my main base chucks were guaranteed to be deloaded. Upon return, 2 dolphins, 4 foxes, and 4 unnamed coraled pigs despawned. Two; the amount of named entities in a given area seem to matter. Naming another entity when there are 35-40 other named entities in the surrounding chunks seems to have a high likelihood of one of them despawning. A note is that unnamed mobs seem to not have a chance of despawning in the named entity cap scenerio. Also despite my wolves and cats making up nearly half of my named mobs, none have despawned. In a week I've lost 6 turtles, 4 dolphins, 1 tamed horse, 4 foxes, 1 jeb_ sheep, and 1 cave spider. And that's not counting how many times the Realm was reset with a backup that restored the lost mobs (and trust me, it was a lot)

I'm getting really tired of this glitch to the point I'm considering not playing again until it gets fixed. I shouldn't have to check everytime I join and leave whether all my mobs are present and accounted for. The fact that the devs are focusing on the Nether and chunk borders also concerns me that the named mob cap won't be looked into.

@Robert Parker: villagers working at the wrong workstation is tracked at MCPE-56889.
@YaYa: villagers changing trades and professions after being traded with is tracked at MCPE-62080.

Those two issues have the same root cause: when a villager dies or leaves or disappears from a village some time after reloading while an unemployed villager is in the village, the unemployed villager will link to the newly-available workstation without updating its profession. Fortunately, that issue is reported to be fixed in the current beta.

@YaYa, re: Parrots and nether portals: what you describe seems to match MCPE-28234, but that ticket is old enough that it would be better for you to create a new ticket. Please include exact steps to reproduce the issue of parrots teleporting to you from a different dimension. The parrots sometimes disappearing partially fits MCPE-66818, so you may want to follow that ticket.

@Danny: the tickets you suggested for Yaya are for Java Edition, so they are not directly relevant.

@Gravity Boots & @Shannon Young: thank you for the video and the new theory about persistent entities moving into a chunk triggering despawns. I will update after I've watched the video.

@Ryan Dussinger: we have a fairly new report open on the name-tagged entity issue you describe. Please add any new information you have to MCPE-101295.

UPDATE: @Gravity Boots: when I follow your video link it says "This upload does not exist."

Re: Why doesn't this bug cause mobs to duplicate? It could be that whenever a mob with a given UniqueID number loads, it checks for and removes any mobs from neighboring chunks with matching UniqueID numbers. This could be part of the normal process for handling a mob moving from one chunk to another.

UPDATE #2: I've tested the nametagged mobs theory and the and the pushing a persistent mob into a chunk with other mobs theory. I made platform with 50 villagers and a few pets all named "Charlie," and I could not get any to disappear with different combinations of saving and loading, nether travel, and pushing new persistent mobs into the chunk.

@Danny yes the chunk saving order idea is similar to what I was guessing too, and crashes/unloading/etc are probably just various reasons the saving procedure is interrupted and doesn't finish normally... @Shannon Young Thanks for the details! It still hasn't caused the bug in my game that way yet - I have some bees which keep flying around my farms in survival- but if things disappear again I'll try removing them first.

migrated 2020-10-22T15:00:43Z

Yea, I'm totally on board with you @Gravity Boots, except my brain keeps getting hung up on the fact it occurs for me regularly on a 1.16 Realms which is lightly used, there might be one or 2 players online. The Realm as far as I know saves itself once some time has elapsed with <=0 players. I can't imagine the save is crashing the instance though....

It occurs during normal save/shut down of servers too, keep getting hung up on the why there too....

I mean it ties into why nether travel causes it too, there's no crash, just the game is forced to save the overworld and load the nether "post haste!" so perhaps in addition to synchronicity in save issues that can be forcibly replicated by crash there is a hole in the natural chunk save order too, probably a refinement of the issue drawing specifically on the inter chunk travel of entities as you concisely explain.

PS> Logged back in after a hiatus last night to checkout 1.16.4, my 2 boat bound villagers stuck in the middle on my lair are still their, patiently hugging each other and grunting occasionally! lol.

@GoldenHelmet

My experience is anecdotal. Honestly, I spend so much time working around this bug so that my kids don't cry over their lost stuff that I really have no idea at this point what works and I don't have time to build a test world and check it 50 times to see if an entity despawns. I just keep adding to the protective measures. That in mind...

Factoid #1: We play in a realm
Factoid #2: I use MCCToolchest to replace villagers and other mobs that are removed by this bug. It's a pain but I'm getting really good at it.
Factoid #3: I have had villagers who were protected and locked by solid block walls into their chunk disappear.
Factoid #4: I occasionally download a copy of the world, turn to creative with chunk borders, and then report back to my kids and their friends about any entities (including beds and double chests - those disappear, too) that they have that cross a border.

Case #1: Chickens (spawned using eggs) and foxes (name tagged) were allowed to move between chunks in a village that was spread across 4 chunks. Villagers kept despawning anyway.

Case #2: I had a 1-chunk iron farm based on silentwhisper's design, build over water. My daughter wanted me to stop killing cats so I modified it to allow cats to survive. She tamed a bunch of them and left the gate into the village chunk open. About 8 of my villagers despawned, breaking the farm.

Since then, I have only built 1-chunk villages using vertical stacking if necessary. I carefully ensure that no mobs (passive or hostile) can spawn in the chunk or move in/out of the chunk. I hid my iron farm so that my daughter doesn't have to know about the cats. I have not had any issues since then.

I originally got to this set of work-arounds by following the comments on this thread. Specifically, the comments related to @Rogue Cheddar's missing librarians.

I would gladly run my game with extra logging or journalling enabled if the devs wanted to trace the issue. I sounds like a thread safety issue and I would think adding extra logging to this that people could submit to the bug would go a long way towards fixing this. I understand such trace level logging would affect performance greatly, but providing a setting to turn it on or off would prevent this from bothering people who aren’t losing mobs and let the rest of us who find the game unplayable without this bug being fixed to get to the bottom of the problem.

migrated 2020-10-23T16:51:17Z

@Shannon Young

Thanks on behalf of all for the report.

I was looking at that iron farm design and considering it for a bedrock realm, how do you find it now you have it hidden and chunk locked? Are you saying the villagers de-spawned because they were able to wander coz the gate was open, or that they were locked in and still despawned?

Having to constantly restock villagers from my villager spawner (trying to keep it 100% legit vanilla as possible so trying to avoid MCC if at all possible) coz of persistence issues was the build or no build deal breaker!

@Thomas Kreeger

Is the save process threaded? surely the latency would be caused by chunks queuing up on the single thread that's doing the saving? I shouldn't comment, I've not seen the source code....

migrated 2020-10-23T17:44:17Z

@Danny

The villagers were locked in place, but there was a gate that kept surface mobs from moving in/out of the chunk. For Iron Golem farm V2, I ended up making my own design that was a combo of a bunch of different versions. I can try and figure out how to create a video tutorial but short version:

1. Lock villagers in and have them stand in water.
2. If building over water, ensure that there is land within 64 blocks to allow (accidental) raids to spawn outside of the village.
3. If building over land, block the entire chunk so that no surface passive mobs can move in/out. (My suspicion about this one is purely anecdotal - belt and suspenders, as it were.)

Soon starting work on a villager spawner, cart transfer system, iron farm and trading hall, but they all need to be a number of blocks away from each other and any villages so plenty of mining work to be done! At those distances I am keen to do some monitoring of this issue, particularly with the occasional loading and unloading of said chunks and the long distance minecart travel I'm gonna subject my villagers too!

Update on this issue BTW, I have chunk aligned my horse enclosure, reacquired a horse, tagged it and tied it to a post with a lead and so far day 7 no incident.

I am close to giving up trading with villagers to get them to master level, I have had several simply disappear or change professions. Today, two farmers, one of them named, both master level, and one of them (the named one) has been in the world for quite some time. They are the only two I have in my 'farm' (enclosed so they can't escape and I play on peaceful, so no mobs to attack them) that trade melon slices. I wondered why the moment I entered the farm I found a new villager without a profession and a baby villager.

The first time this happened was some time after the Nether update - we found half of our villagers had simply disappeared, changed professions or were back to novice level. It now just randomly happens from time to time - that famer we had no longer exists, the four stonemasons are now two but we have a random extra shepherd... We are no longer surprised each time it happens, just irritated. The point of trading is to lock them in to their professions, and the point of naming them is so they don't despawn. I've pretty much given up on trading for the time being till this is sorted. It's just frustrating.

I am not sure why my ticket was directed to this thread. It was about despawing named mobs and villagers. However this only refers to chunk border issues. The problem i am having is in the middle of a chunk. Unless the work around they listed doesn't actually solve the problem

migrated 2020-12-04T15:17:21Z

I'm pretty sure this thread is for any entities disappearing upon save (now), it just happens more often close to chunk borders

GoldenHelmet 2020-12-04T16:48:09Z

@Hunter Haasch: read the 2nd paragraph in the description.

migrated 2020-12-05T08:27:23Z

Read the issue. Because I did read the second paragraph and it says groups despawn in chunk and persistent mob despawn at border. Recommend fix is to not place near chunk borders. So I clearly state again I am not sure why I was pushed together with this thread. The Recommend fix is and I quote" We are still working on a solution for this issue. Currently entities can end up being lost if they happen to be positioned on the boundary between two chunks when the game crashes. One workaround for this is to position mobs away from chunk boundaries, which can be calculated using coordinates." So it has nothing to do with a resolution for my issue.

@Hunter
Hi. I have mostly given up on this one but buried in the comments are examples of entities disappearing that are safely locked within chunk borders. My own examples are with missing villagers in a realm that my kids and their friends play in.

I have also had villagers and other mobs that are locked to a single chunk despawn. It’s super annoying and I agree that the description does not accurately convey that even if you carefully lock in your mobs, they can still despawn. There are two approaches that the kids and I use- first, accept the things we cannot change and second, protect where something is really valuable and time-consuming to set up.

That said, I have a set of work-arounds that seem to work. My experience is with villagers but it applies to other mobs as well.

Trading Villages:
1. Design so that all villagers are in a single 16x16 chunk.
2. Use solid block walls around the borders with gates to keep any other entity from spawning in the chunk and then moving out of the chunk. (Cats, passive mobs, etc)

Alternatively, you can also design a multiple chunk village as long as the villagers can’t cross chunk borders, can’t breed (no framers) and there is no grass (passive mob spawning). This is harder to get right, though.

Iron Farms:
1. Build on a small island or over water - somewhere that is close enough to land for raids to spawn outside of the borders but far enough away that neither passive mobs nor other players may wander in and out of the chunk loading area.
2. AFK from the same chunk as the farm. AFK for a long time after making the farm in case future versions of the game break the farm.
3. Build out your water trap beyond the “center” of the chunk bc the village center will move every in-game day.
4. For a 16x6x16 volume around any possible center that is not inside the watertrap, have only solid blocks (underground) or air (above ground).

silentwhisper has a design for a 1 chunk farm that can be adapted to meet these requirements.

Breeding Villages:
1. Use a 1 chunk design with solid walls.
2. Put your farmers in one section and use a 1 block high trap door drop through for the babies.
3. You can send them to the nether but frankly, I find it easier to use a watertrap under an area with beds and wait for the babies to grow up.
4. Once they are grown, filter out the nitwits (either kill or drop through water trap and let drown do it.)
5. Use boats or minecarts and the watertrap to move adults to a different village.
6. Lather, rinse, repeat.

Hostile mobs:
Nametag them. “Interaction” is not enough to keep them from despawning, in spite of what the wiki says.

Passive mobs:
Lock them in using solid block walls and gates at the chunk borders.

GoldenHelmet 2020-12-05T20:38:26Z

I have replaced the workaround panel and some of the description text to try to make them more clear. I also updated the out-dated statement about interacting with mobs. Sorry that what was there was confusing or misleading.

@Hunter Haasch: What you describe in your report (REALMS-6288) is exactly what I meant by "groups of mobs in a chunk disappearing". The resolution of your report as a duplicate of this one is correct.

migrated 2020-12-05T21:33:14Z

@GoldenHelmet Thanks for updating the description.

The description should also include reference to MCPE-71243 and MCPE-101202 which are related to the "appearance" of villagers despawning but with the difference that if you use MCCToolchest to inspect the data, you discover that they are either (a) positioned in walls (but not suffocating ¯_(ツ)_/¯ ) or (b) present but invisible. Having all players exit the realm for 15 minutes is the current work-around. Additionally, these issues are new in 1.16.100, fixed in 1.16.200-beta, and unrelated to chunk borders.

I’m on the newest version and I had a village where all but one of my villagers were killed by mobs. So I brought a villager from their village to mine and then they disappeared. I thought it had something to do with villagers not being able to move villagers so I cured a zombie villager and it was successful so I bred them with my other villager and they had two babies. The next day after the night I noticed only the original villager was there and all my other villagers were gone. Even the one I cured. They couldn’t have died cause I’m on peaceful. I’m on iOS 14 on iPad

migrated 2020-12-18T13:17:01Z

Hope this can add some info

For me, a horse, donkey and their mule offspring despawned suddenly. Before this, a jeb_ sheep was free roaming with them in their enclosure but also despawned. The horse also had a name tag so clearly those don't work in this situation at all.

migrated 2020-12-23T04:17:16Z

I'm relatively new, playing MCPE. This is a consistent issue for me. I've probably lost hundreds of villagers from random despawning, dozens that I've lovingly leveled up to Masters, sad face.

I recently noticed a sheep that I had in a fenced area despawn as well.

I've added nametags (Doug the Librarian) and theyve still despawned.

I'm also in peaceful so no hostile mob murders.

My village recently went from maybe 20 villagers to maybe... Two professions and three nitwits. This is incredibly annoying. 😣

Playing on the latest minecraft bedrock version, on a rrealm (1 player on switch, 1 on win10)

We had 2 name tagged, saddled and armoured horses disappear in one week (both were leashed to a post) . It happened between logons, and the leash graphic was left on the post (it disappears when clicked, but does not return the leash item).

Its very frustrating because we lost all our saddles like this. I understand from reading through comments here some people are saying it should not happen to name tagged entities, so I am just here to say it can and is happening to name tagged entities.

Attached is a pic of how it looked (not my pic but taken from another user on a duplicate of this issue)

For me, villagers (with nametags and having traded with) in my artificial village will despawn after i return from a long journey away from my base.

The first time i noticed this I managed to catch them in the act of dying since i restored a world backup and it was a mistake on my end due to them being suffocated on their homes' ceilings since they hopped on their beds and i made the ceiling too low, but since then I fixed that but they keep dissapearing again.

If I stay close to the village, they don't seem despawn. I'm using the latest bedrock server for this world (1.16.201.2)

mcconcma 2021-01-03T17:08:47Z

We had noticed passive animal mobs (sheep, cows, pigs etc) disappearing in the past, but last night was the first time that we saw villagers disappear that could not be explained by other possible issues (the villagers flying out of beds issue from a month ago).

Villager Set-up: We have approximately 19 villagers, each contained within a 3x3x1 (three deep, three high, 1 wide) "cell" with a bed, and one block of free space. All cells are lit and the entire "trading hall" is lit. There has never been any hostile mob spawns in our hall. We have one additional breeding section that is approximately 8 x 3 x 3, also well lit. This area contains 3 villagers, workstations and beds. This area is completely walled off.

All villagers have been traded with and have professions/beds to sleep in. The entire trading hall (25x3x8) has a captive portal exit, so one has to purposely try to let the villagers out for them to escape. There are no other villagers within 200 blocks of this area.

We had a game crash two nights ago, but had traded with these villagers since. When entering the hall last night, we had lost 4 villagers. Two villagers from the cells were gone, and 2 of our 3 villagers in the breeding section were gone. I tried breaking/replacing the beds, and they didn't reappear and there were no sparkles. I released a villager from it's cell and opened the breeding doors, fed them some bread and they immediately filled the 4 available beds with fresh kids. Somehow, the 4 original villagers are gone or too far out of the village to have claimed any beds.

I need to check my chunk boundaries, but based on the position of the villagers lost, I'm not sure this is a chunk boundary issue.

This hall has been very stable for quite some time, to the point where we have barrels above each "cell" to contain the books/trading items for each villager. Replacing the 4 villagers last night caused us to have to remove all barrels so the new kids wouldn't link to them as fishers. Resetting new librarians is also a pain in the butt when you are looking for a specific book trade.

I'm crossing my fingers that this is a one time thing, and doesn't happen more consistently.

I don’t understand what’s going on. I’ve been playing Minecraft on and off for a while and I recently got a pc and got the windows 10 version of Minecraft. I joined a friends world and they lived in a village with no villagers, they said the the villagers disappeared. We made a new world and played on it for quite a while, made a home for villagers and even managed to roll a mending one until one day we went online and there were no villagers which is so frustrating. Then again, we don’t wanna live in a world with no villagers and it happened again. Now this post is saying that I have to learn what a chunk boundary is and I have a 1 in 20 chance of a villager despawning for no reason??? The villagers have always been in village boundaries and near the bell. The latest case of this happening to me was I went to sleep, came back to the villagers beds and all 10+ of them were just gone.

osfanbuff63 2021-01-10T13:31:07Z

I have been having this issue since 1.16.100 came out with cows and sheep, but just recently in 1.16.201 hopper minecarts have been disappearing when we unload the chunk that our supersmelter is in, and in 1.16.200 and 1.16.201 villagers had been disappearing in one world but in a different one villagers have not disappeared at all!

I can confirm this bug. It happened when me and my friend cured a few zombie villagers (we were not near any natural generated village, so we cured these ones that spawn at night) and built houses for them. A bit later, we stopped playing and we hit Save & quit. When we came back, the houses villagers lived in were empty.

My minecart with hoppers keep disappearing in enclosed tracts. The minecart goes back and forth collecting. They just vanish. All of them. (I only have 7 around the village) but they all vanish at the same time which is annoying use of iron. This is happening on ps4, realms

I recognized the same issue as osfanjoshua.

At last two villagers disappear from chambers in a trading station and in my breeder, minecards disappear from their farm rails and cows from their enclosure.

migrated 2021-02-15T01:22:58Z

I was getting around this issue on Realms Plus by loading backup files when villagers vanished but sometimes had to go back in time farther than the last time I actually witnessed the villagers present. Also, I could reliably create a vanishing villager by reproducing villagers. However, not reproducing villagers did not always prevent them from vanishing. This suggests to me that there is a bug in an index to the villagers. This is current as of two weeks ago. I finally canceled my subscription because if this doesn't work then, like, what's the point?

migrated 2021-02-15T01:24:42Z

Oh, and the workaround isn't helpful without debug mode to show us where the chunk boundaries are. However, as pointed out by the reproduction experiment, it isn't totally due to chunk boundaries.

SirDaddicus 2021-02-16T05:05:36Z

This happens to me quite frequently. The village is walled and there are no open caves or water. I've searched every inch of it, and the villager is simply gone.

Sometimes, however, the missing villager will return. I can tell it's the same one because I promoted him.

Other times, he'll return, but has been gone long enough that another (new) villager has stolen his job site block. In these cases, I can simply break the job site block and come back a game day or so later, and put it back when the old (promoted) villager is nearby.

But other times, they're gone forever.

This has GOT to be fixed. It costs an enormous amount of resources to promote villagers to master. It is unacceptable for them to simply vanish from the game.

EDIT: I am running Java 1.16.5

@astrokitty, it is the same bug. I lost numerous villagers and horses in single-player and multi-player (locally hosted, not realms) on Xbox One. Eventually stopped playing in 2019 or so because so much work was wasted. Game-killing bug now 4 years old.

Is there any chance this will be fixed soon? All my current projects require villagers to be able to cross multiple chunks.

Does anyone know of any workarounds?

migrated 2021-02-23T16:17:16Z

@Mew and Minami, you could continue your project, since this bug isn't always that common. Try staying near your villagers and avoid going to the nether. This isn't a guaranteed workaround, but maybe you can look closely and see if your villagers are despawning even when you are right next to them.

migrated 2021-02-23T16:40:48Z

@astrokitty – In my case, the issue is happening 3 to 4 times a week...

Also seen when interacting with villagers. In most of the occurrences, the Minecraft Bedrock server crashes and when re-opening it, some of the villagers are gone! So staying near the village is not really a workaround.

I proposed to collect whatever logs post crash they would need to investigate. No response... Unless they have the fix and did not tell us it's implemented and being tested, etc....

SirDaddicus 2021-02-24T02:38:56Z

I found another possible culprit today. As I walked through my village, a villager was stuck in a tree. It shouldn't have been possible to walk there, as there was only a 1x1 corridor running under the leaves, and dirt next to that. But, there he was. I think he was suffocating, but couldn't really tell. I cut away the leaves from around him, and he happily walked away.

SirDaddicus 2021-02-24T02:47:18Z

Another possible culprit, although this one is probably by design.

In the village there's one of those tall cobblestone church buildings. They have a ladder going up to the roof. There at the top of the roof was a villager, and there was a second one on the intermediate floor. Neither would leave those areas (I waited through a day/night cycle, when they should have tried to get to bed.

So, I nudged one of them to the ladder and he went down. The other (the one on the roof) instead jumped on the battlements and fell off, outside the village.

I was able to rescue him, but I could easily see a villager dying from that kind of fall.

migrated 2021-03-07T01:20:56Z

I have a “villager apartment” with a two fence high wall around the perimeter, and my villagers are constantly despawning. I know for a fact they are not dying from mobs, as the area is super lit up. I play on a realm that my household pays for, but we have several friends who also play at any given time, so it’s unrealistic to have someone just sitting with the villagers if someone is on the realm. Can we please get an update on this?

@Alex Groot, so this means this bug is not only caused by mobs crossing chunk borders. Did this ever happen before or was your horses despawning recent?

migrated 2021-03-09T22:16:24Z

@astrokitty, your calmness and optimism are admirable. I wish I was more like you in situations like this. Please continue with the positive vibes.

I speak from some experience: there are no bugs which are four years worth of "hard to fix". Not in waterfall, not in agile, not in DevOps. If it takes four years to find and fix a bug, then the bug isn't the problem. The problem is a failure of process, governance, and/or prioritization. This community has provided almost four years of tests, screenshots, examples, ideas, and workarounds, but we have not a single developer comment on bug-finding progress, nor a single patch directly for this bug. GoldenHelmet actually provided a sample world and repeatable steps! But...nothing. If I were more like you, I would not presume that they are more concerned with new features and "dungeons" and spin-off properties than they are about killing this game-breaking bug. Sadly I'm not more like you, so that is indeed what I presume. It's not credible to me that developers have been actively working on this bug for four years with no progress.

But I'm going to try to adopt some of your spirit, astrokitty, for the next year of waiting.

migrated 2021-03-10T15:31:56Z

I have noticed another issue in my experience with this that is starting to zone in on the issue:

My friend hosts the world where we have used name tags on many mobs in order to keep them around. However, many of our animals have despawned. I tried building an aquarium and a zoo, and some animals are specifically tameable (wolves, ocelots, parrots, etc) while others aren’t (sea turtles, polar bears, mooshrooms, etc). Our named tameable animals and enemies do not despawn - but our untamed animals do, despite having been given names. I wonder if it’s an issue with Name Tags not properly interacting with untameable animals. We lost fish, a sea turtle, a polar bear, and more over the course of a few days, while we’ve had a named Slime in the world for about a year now. It doesn’t make sense and it’s extremely frustrating, especially when your biomes for obtaining those creatures are over 7000 blocks away. Our base is at X.100, Z. -300 approximately. Our jungle is X.900, Z.-10,000. We worked very hard for our efforts to disappear when we weren’t looking. It really, really sucks. This needs to be fixed - the fact that fish can be put in buckets and bears, foxes, mooshrooms, and such can be attached to leads is just the designers begging the players to keep animals in their worlds, but it doesn’t work. It needs to be patched.

Also, I was looking at some older comments and I just wanted to repeat some important info to anyone else saying what happened to them. It was said that mobs that move a lot are most likely to cross chunk borders, which is why they despawn the most. I'm talking villagers, minecarts, and bees. This is also why more stationary entities, like armor stands, don't despawn much from this bug.

@fp, there is no real solution to this bug, but it would help if you prevented your horses and villagers from crossing chunk borders by enclosing them in a fence or pen that is only in one chunk (16x16 blocks). You could also avoid going to the nether, because that also causes this problem. This won't guarantee your mobs not despawning, but its the only thing you can really do to help.

Now my mobs are randomly disappearing or getting burned up where they've been safe for years(I know they've been burning up because I have hoppers underneath them). Now the sheep in my automatic shearing machine are disappearing which is extremely annoying because they've been in that thing for over a year. Now I have to dismantle the machine to put new sheep back in, but I don't wanna go through the trouble of doing that if they're just gonna disappear again..

I was playing split screen with my bro and I was on a horse and my bro was on a donkey with 4 stacks of books which we were taking to a village. The game crashed on the way (bad xbox it happens) and the horses and donkey weren't there when we came back. Its possible they somehow wandered away while we were offline and we could find them but I think it despawned. We still reached the village then left and then i came back a week later to find all the villagers in that village gone even though they were way out of render distance so a zombie siege couldn't have happened.

I'm glad I'm not the only one having the issues in the MCPE edition of Minecraft. My sheep have despawned in a fenced in area within my house 1 cow disappeared or despawned from the same area and two chickens as well as one pig have also despawned. I only had two of each of those animals anyways. 1.16.210 on Windows 10 is where it's mostly happening for me. And I'm playing solo.

SirDaddicus 2021-04-05T16:05:31Z

My original post seems to have disappeared. This is a reproduction.

This problem is almost trivial to fix:

Find the despawn algorithm(s) in the code.
Add a list of non-de-spawnable entities (entities that should never despawn).
Check the list each time the code goes through the despawn algorithm.
Skip out of the algorithm if the current entity is in the list.

Some entities which should never despawn:

Villagers
Minecarts
Horses
Donkeys, mules, and llamas
Probably some more

@Jim Gersetich, they deleted my reply to you as well. They do not allow discussion of the bugfix here, only reports of entities despawning unexpectedly. With only one or two more years worth of nearly identical reports they'll have enough information to attempt a fix. It is likely that your post and this one will be deleted again.

My response to you prior was, in short: we should not assume that the solution is trivial, especially considering the behaviors people are witnessing. Even one of your own reported behaviors points not at the vanilla despawn algorithm, but at more complex problems.

It seems that when there is thunderstorms some mobs and enitities despawn.

so far and these have been indoors the following have despawned.

2x iron golems.
1 x pig
2 x Armor stands

all after a thunderstorm

I feel like fixing this should be a priority. Nevermind the unnecessary constraints on technical builds, which drive me crazy, but I can learn to (mostly) work around. But, I've been building a mob zoo on a family server with my 5 year old niece, and her zoo animals keep disappearing. This just seems completely unnecessary and it makes her sad, which makes everyone sad ...

migrated 2021-04-08T21:47:23Z

This happens so often on my Realm, we now are limited to not allowed any mobs (even horses and Villagers) to go near chunk borders. It happens most often when a player logs in on a Nintendo Switch. We have lost Villagers, Horses, Skeleton Horses, Donkeys, and other nametagged animals (such as chickens and cows) to this bug. It really limits gameplay when you constantly have to build around chunk borders and pray your animals and such won't disappear. I really think this should be a priority, as no one likes it when their prized Mending villager disappears (yes that did happen to me lol).

migrated 2021-04-09T16:02:53Z

Heres something about this I havn't seen anyone else mention : sometimes the mobs (or at least villagers) will go invisible before despawning. It will look like I have no villagers and that they all JUST despawned, but if I ring the bell all the doors will open and close, Aas if they are still there. They will only be invisible for like 2-3 minutes before they despawn, and a lot of the time they will just go straight to despawning.

migrated 2021-04-13T21:56:11Z

For me this happened twice now. First every chicken in a world just despawned at once - from 4 hen-houses/pens that were loaded (possibly after a thunderstorm. Not sure about that). They even disappeared from an auto egg farm (4 chicken standing on a hoper in a 1x1x1 space fully enclosed and roofed... It was impossible for these to cross a chunk). And today, on another world, all hares disappeared from within a fence (there was a thunderstorm).

We are on Xbox and we play offline splitscreen. There is no way for us to reliably track/avoid chunk borders should that be the issue.

migrated 2021-04-14T01:17:34Z

I truly wish that this problem could be fixed as soon as possible since have lost way to many animals by now and my sister that just started playing game have now lost her very first horse.

I've recently lost one of my guardians to this issue. I've gotten used to my village cycling through villagers now. A few of them will be replaced as suddenly as they disappeared. This was fine until my best villagers started despawning and more villagers were disappearing than being replaced. This eventually caused my iron golem farm to stop working. A large amount of villagers (about 20 out of 50) are farmers on a large carrot farm so they provide carrots to the population, allowing them to breed without my intervention. Luckily, things returned to normal after a few weeks.

Also, does anyone know if this bug affects shulkers?

GoldenHelmet 2021-04-16T16:33:46Z

@May Linn: thank you for sharing your observation about villagers being invisible. Could you provide more information?

Has this happened like you describe more than once?
Is this on a local world, server, or realms; and single-player or multi-player at the time it occurs?
Are you on the latest version (1.16.220)?
Does this comment (about villagers sleeping outside of their beds and appearing differently to different players) describe what you experience?
What were you doing before you noticed the invisible villagers? A full account of that play session would be helpful.

What this sounds like is the villagers being loaded by the server but not by your client. If it's in multiplayer/realms, it could be due to different versions of chunk data being loaded for you vs. other players. I have experienced this with blocks on a realm: my son once built a wall and asked me to come look at it, and when I got there it was invisible on my screen and I could walk through where it should have been. Obviously my client had loaded the chunk before he built the wall and either his client had not saved to the server or mine had not reloaded from the server since the building started. That kind of error could conceivably cause mobs to be deleted.

@Jim Gersetich:
The problem here is not trivial and nothing to do with the normal despawn code. The bug is that "despawning" happens in spite of the kind of check you suggest, which in fact already exists in the game. Mobs that should not despawn have a data bit called "persistence", which is checked by the despawning algorithm. As MD pointed out, if villagers and ridden/temped/bred/name-tagged mobs were not checked as to whether they should despawn, then they would always despawn when you moved away. The problem is that there are ways entity data can be unintentionally lost from the world save. If you want to get an idea of the complexity of this kind of issue, have a look at this comment explaining how horses used to "despawn" if you logged out while riding them in Java Edition.

migrated 2021-04-24T08:51:10Z

I have just experienced this after updating to Bedrock V1.16.221

Playing on a Bedrock realm, I had logged in and out a few times whilst building so I could look at a reference on a creative world, after a while I realised that some villagers were missing, I had a look around and something like half the villagers and animals near my base were gone.
3 of 4 villagers, 1 of 2 iron golems, 10 of 16 sheep, about 10 of 16 cows, 1of1 horse, 3 of 3 rabbits. Some cats and a dog were unaffected.

The villagers and golem were free to roam, but the cows and sheep were confined to pens.
I was working near the villagers and sleeping through the night, so I know they weren't killed.
The animals had been in those pens for weeks with no escapes.

I guess they disappeared when logging out then back in again, but can't confirm.

I trapped a zombie villager in a minecart and gave him a wooden sword via a dispenser. It was obvious he was holding it and picked it up. I sent the zombie villager down the track and he despawned immediately after reaching the despawn distance taking the wooden sword with him. I did the same thing dispensing an iron helmet the second time, and the zombie villager despawned immediately upon reaching the despawn limit. The only way the zombie villagers have not been despawning has been to use nametags. Merely holding an item has not been enough.

I have also lost many passive mobs, mostly cows and pigs.

GoldenHelmet 2021-04-26T20:00:13Z

David Jones: apparently giving mobs equipment by using a dispenser does not give them persistence. That's not what is tracked on this ticket. I have made a new report for it at MCPE-126494.

I just had a horse mysteriously disappear from a fenced area when it had a name tag, a saddle, and was wearing DIAMOND armor. It exceeded the criteria to not despawn, and what happened? It still did, along with the diamond armor...

I can confirm this. This has been wreaking havoc on my SMP's villager trading hall. We lost half of our name tagged villagers in one crash alone. Weeks of work instantly gone.

Same with me with the disappearing villagers, sheep and minecarts. And newly bred and grown ones are continuing to despawn during the same RL day. I am playing on IOS in a (currently) single player world. Survivor/Peaceful Modes 1.16 still. Luckily, I had made a copy a couple of days prior and was able to start over again from there. I have been saving a copy daily now.

Same with me. Lost some dozens of animals (chickens, cows, dyied sheep and llamas with carpets and chests) after exiting my realm. They were all in enclosed fenced areas, open air, on sea level, over grass and dirt. Not name tagged, but all interacted (fed and/or tamed). Not all animals disappeared, some were left.

I play on a Realm and we've been noticing minecarts disappearing for weeks now - normal minecarts (used to collect xp from a gold/xp farm, coal/wither skull farm), hopper minecarts (wool farm, super smelter, various other farms). It's ended up causing ridiculous lag and annoyance at times due to entity lag and having to replace them

migrated 2021-06-06T06:19:44Z

This problem is not exclusive to realms, i have a zombie spawner farm and i cure the zombie villagers to create a villager trading post under my base at y15. When i leave my base or go over ground, i always deactivate the spawner and have placed carpet all around it to so nothing spawns yet when i come back to my base all the villagers and player interacted mobs including a tamed fox and a red coloured sheep disappear with no sign of them existing besides the emeralds i traded with them. The confusing thing is that i have a villager (with mending) a hundred or so blocks away from my base, yet he has not despawned. This has now happened 5 separate times in the span of two days, to the point where im just fed up.

This also happens after a crash which for some reason has become common after the recent 1.16 patch. Also im playing on ios. Has also happened with with blocks like slime and items like warped fungus on a stick

migrated 2021-06-06T16:09:30Z

I have several animal pens that are chunk-aligned to prevent this. I logged in a couple nights ago and in the pen of cows, about half of them were suddenly gone. I think this may be somehow related to changes that were made to entity despawn radius - many mobs will now despawn when you are within a couple blocks of them on your way to interact, as though despawn is based on a timer rather than a radius around the player. The same thing could be ignoring the interaction check.

migrated 2021-06-11T16:07:08Z

This effects entities going through ender portals too. It seems to happen because the player's coordinates are set before you actually enter the end & before overworld chunks are unloaded. This causes the pet to teleport to the owner's coordinates(around 100, 40, 0), but while staying in the overworld. The pet can be found in those coordinates if you return to the overworld.

migrated 2021-06-18T17:30:39Z

mobs are disappearing even if they are tamed, named, interacted with, inside a pen, bred, traded with, and on leads. Here is a list of the mobs that have despawned in my realms world playing on PC windows 10 version.

many dyed sheep that were bred in pens vanished

tamed horse with saddle attached to post with lead

many tamed horses with saddles in pen

A named polar bear in a pen

foxes that were bred in a pen

ocelots that were bred in a pen

multiple captured villagers that were traded with to max level and named

a named endermite in an enclosure

This has been very frustrating as many resources were spent on these mobs such as name tags, saddles, dyes, and emeralds. Also spent hours traveling thousands of blocks to obtain some of the animals. nametags are expensive to trade for and difficult to find in world especially since all areas explored that are close to spawn we have already looted. I want my nametags back and my jungle friends as the jungle was so far away to travel to and took a lot time to bring them back to spawn

I logged into my realm and was missing 2 named and saddled horses. This is now seven different named and settled horses I have lost, including to the head armor quit. I also have lost approximately 15 to 16 villagers that were level two or higher as well as anywhere from 6 to 10 named colored sheep.

This is for 1.17.1 on the Switch, but I also noticed it before the hotfix. No realm, just a standard, lone Creative world.

I'm in the middle of making a pretty sizable zoo build, and have had mobs, all of them named, despawn multiple times. It's frustrating that whenever I reload my file to continue building, a good chunk of my mobs randomly disappear. There are three max in each habitat except for the pandas and parrots. It's Creative, so it's not as large of an offense, but it's still a constant that I hope gets patched out.

But a quarter of my colored sheep are gone. Walls are too high for mobs to get to them. Foxes don't eat pigs, right? But they keep spawning into my compound, so it's possible they are spawning right into the sheep pen?

In my realm entities keep despawning when they shouldn't. My villagers keep despawning, even after I name tagged them. Today I had like 5 axolotls despawn after they were placed in an enclosure from a bucket, what I noticed was that it happened when the realm loaded the area because no one else was online and some of them disappeared when I joined the realm a couple of times. When I first left the realm there were 5, then I came back and 2 were gone, left the realm again, join back in and more were gone and so on until there were no axolotls left. Please fix this problem as it's making the game not enjoyable for us since now everything we do has to have in mind that entities might despawn randomly.

Voted for this bug.
My server has many players reporting issues just like this, and I'm affected the worst having built a village in the Nether.
I dread leaving a range of my village that would put it outside of the loaded chunks zone. I can AFK in there for a whole 8 hour workday and all my villagers will be fine, but if I pop out to the overworld for 30 minutes and come back I can lose anywhere between 1 and 6 villagers.

migrated 2021-07-04T00:54:14Z

It’s not just the odd horse. My poor zoo. After painstakingly gathering polar bears, goats, turtles and every mob I could find, I’ve given up. Glass enclosures are eight blocks high and don’t cross chunk borders. I’ve run through half a stack of name tags. Useless. Eventually I return from the Nether, or some far off Overworld mission, and seven axolotls have become five, then two, and eventually…empty cage. Or my Mending librarian has been despawned and will be replaced by a brand new villager. I held out that 1:17 might solve this issue, but no luck, so at this point I’m pretty burnt out. Would be really nice if someone could fix this.

I am beyond frustrated with this bug in my realm. I can't keep any farm without all the animals eventually despawning and believe me It took forever to get all the colors of sheep. I can't rely on trading with high level villagers because they all despawn before I can increase their levels. None of my automatic farms function very long before both the villager and the mine cart disappear out of nowhere. I don't even go that far away from any of my mobs for very long usually but they continue to despawn. Nothing I try is working, and I've tried downloading my realm and overwriting the current realm with the new one, I've tried name tags, I've block villagers in cages but nothing gets better, in fact it has gotten worse. Its a wast of money to keep my realm open if all of my mobs are going to despawn no matter what I do.

How has this not been fixed yet? I only just bought my realm about a week ago, and the village I've been working on has basically been abandoned entirely. All but 1 of the villagers has despawned so far, including several named/traded with librarians. I even lost two villagers that I had named in honor of my grandparents in the realm my uncle is hosting.

Currently running V1.17.2 Bedrock.

This bug is making it entirely pointless to try and level up villagers for good trades (or memorial as is the above case) if they're just going to disappear out of nowhere. And since it's Bedrock, I don't have access to the same console commands/debug options like I do with Java to find chunk borders easily to try and prevent cross-border movement. I get that the studio is still working on Caves & Cliffs Pt2, but this NEEDS to be fixed ASAP, and not just given some shoddy work-around that A) isn't guaranteed to work, or B) Isn't easily made possible depending on the version.

Why are people’s comments here being deleted? This is a major bug that breaks Minecraft. Mojang used to boast about not wanting to break the player experience or disrupt their world but it’s already been happening for months and continues to happen every single day. This bug has effected my worlds both on realms and in single player games I played just today on the latest version.

Dr.Awesome4333 2021-07-08T01:54:45Z

Comments that do not add new information or otherwise do not comply with our guidelines will be removed.

Quite honestly, I know this bug is pretty game breaking and has been in the game for years, however complaining about here in the tracker accomplishes nothing. If you have new information regarding the issue, feel free to comment but comments that just say things like "this happened to me too" do not help get the bug fixed faster.

A few reproducible cases of this issue have been found, however those do not seem to be the only ones around. Feel free to experiment to see if you can find more reproducible cases of mobs despawning when they should not.

migrated 2021-07-08T03:51:34Z

Then you need to talk to your PR team, Dr. Awesome. Bc deleting comments looks bad. Look, I'm a developer, I know it's cluttering up the ticket. But Mojang is otherwise silent on the issue, and no mods or devs have said anything about progress for literal months. Fans want to know they are heard, but it doesn't feel like Mojang cares in any way about what even you admit is game breaking.

I know bugs where you can't be certain how to repeat are the most vicious and hard to do anything about, but when devs say nothing and the company says nothing, users are left only to feel that you guys don't care.

I suppose this comment will be deleted too, but I just needed to let you know that this problem is bigger than an in-game bug. You have a PR bug, and the only fix for that is to make sure users know Mojang/MS are putting effort into fixing the code bug.

In attempt to save this comment, let me point out something that you could be using the chatter for, even from a bug ticket perspective.

1) Reproducing this is clearly not a simple {{if A and B then C happens immediately }}— because hyou don't know what A and B are. You don't even know if it's just A and B or if it's A through E.

You're going to have to reproduce actual play conditions. Which is not clean like most bugs. And this means looking into comments when people say, essentially, "me too" – if that's ALL they say, ask for more detail. Your team should be hunting for the details, not casually waiting to see if you get lucky and a user reports something easy. If they posted, they care enough to comment, which means they may be willing to provide more if they are prompted.The only thing that makes a bug unrepeatable is not knowing the conditions.

I'll volunteer what I remember of my situation.

I built an enclosed glass structure 18w x 18l x 10h blocks (interior measure). it was filled with water to a depth of 4 blocks, and at the time of the first incident, it contained three turtles and 4 axolotls – all seven were named. The was a small amount of land at the top of the water, so both mob types could leave the water if the AI so chose. The entire enclosure was located inside a warm ocean biome and was completely submerged.

A few days later, 2 drowned spawned inside the enclosure. When I showed up, one axolotl was playing dead, and another was missing. I assumed it had been killed by the drowned. I killed the drowned and put more lighting in to prevent hostile mob spawning.

The next time I left and came back, the previously wounded axolotl was missing as well.

The next day I caught another axolotl and named it. Then I bred 3 more (which remained unnamed). At this point I had six axolotls that I had interacted with by breeding or naming.

Two days after that, all six axolotls disappeared. Apparently at once. I had been mining and shaping the immediate environment (removing dead coral, planting live coral, mostly). None of the turtles have ever gone missing.

Note that this isn't a quick repeat. You might have to let devs or testers play for a while to see the bug, and log every single thing that happens in that time. It will mean slogging through tons and tons of data. But frankly, you have a 4 year old bug that breaks the game and infuriates the users. Your current approach is insufficient.

1b) Note that developers or mods asking for more details shows the users that someone is actually paying attention to them. It will help your PR problem at the same time.

2) You could also tell marketing, business, and customer relations about every single report. I know that at my job for a national bank with thousands of customers, if we report every time a customer complains (esp if they're all complaining about the same thing) then the problem becomes a priority pretty quick. Resources get allocated, and fires get lit under people so they put more attention into the issue instead of doing the "insufficient data, not my problem" thing.

As it is though, all the users have is this one Jira ticket, which has almost no mod or dev interaction, and the bulk of that interaction is deleting comments. You're alienating your user base which reduces the game popularity. As I said before (the comment was deleted), the action I'm getting closer to taking is not buying the Java Edition for my new computer. It's dropping Minecraft all together.

I have a realm newly created a few weeks ago, no cheats, with a walled lighted village. Had up to 5 iron golems all now despawned, tamed horses de spawn frequently, sheep are despawning almost as fast as I breed them, villagers too. New villagers do spawn but have to be levelled up again. Mobs in general despawn quickly especially horses which are now almost extinct anywhere in the world. Oddly I’ve only encountered Pillagers once in many hours of activity. This morning I’m faced with levelling up all the weaponsmiths from scratch again. We access the realm from both iOS and Windows. Happy for Mojang to use my realm form debug.

I found why this happens its because for some reason villagers have the ability to lose their jobs as soon as the host or creator of the world leaves the game which is MCPE-134915 as a result of this they can de-spawn because they have no job or they will switch workstations breaking many farms.

Z: villagers do not despawn just because they have no job. Villagers are always persistent, which means they would never despawn if the game were working correctly. See for example the list of mobs that do not follow despawn rules in the 1.16.0 changelog.

I play on a Realm but did not notice mob loss until after 1.17. It seemed like there was the major 1.17 update then a smaller one a weekish later. The mass elimination of mobs seemed to accelerate after that second update.

Complicating my complaint is that I invited a second player to my realm around the same time. So if logging in and out can despawn mobs, then perhaps they helped encourage the slaughter.

Done some tests, and I found out it has nothing to do with crossing chunkborders.

I locked a villager (mending for 14) in my house in a one block space, so he can not walk anywhere. (see my two screenshots)

[media]

He was there many (realtime) days playing MC.

I gone to the nether, and came back in Overworld

Travelled far away in the Overworld and came back via Nether, or in the Overworld.

He was always there!
But yesterday, I slept in my bed - woke up - he was there - go downstairs to my storage room (5-10 blocks) under my house - came back after a few seconds because I forgot a shulkerbox - and he was gone!
He could not walk over a chunkborder, the chunk wasn´t unloaded or something — but he disappeared just because!

Ok just a little bit later I use FoxyNoTails Armor Stand Plugin and looked at the chunkborders where "Rolf" standed.

Maybe it´s useful: Where "Rolf" standed, there are directly behind the chunkborders.

He had could touch it, but not cross it.

Screenshot is uploaded. (The white stripes showing the chunkborder)

I did an experience: subscribed for another Realm, where I uploaded a copy of my original world from the original Realm, wich experiencied massive despawning of spawn-proof entities for a long time. In this new Realm I killed and destroyed some of the old interacted mobs (villagers, animals) and some of the old entities (armor stands, minecarts), and replaced them with new ones, in the same conditions.

After some days travelling to the Nether and far away chunks in the overworld, no one of the new entities despawned so far!

By the way, there´s a new pool in r/Mojira, where someone is researching the impact of the bug. Please participate! => https://www.reddit.com/r/Mojira/comments/ogy9vc/counterexamples_for_mcpe21416_despawning_entities/

Dr.Awesome4333 2021-07-13T19:42:12Z

When you slept in the bed, did it change your spawn point to the bed from a different spot or was your spawn point already there?

migrated 2021-07-13T20:13:29Z

That´s a good question.

Unfortunately I can no longer say 100% whether I slept in this bed before or whether it was the first time after a trip.
Yesterday I built a lot of things far away from my base - that's why I also needed the Shulkerbox for other materials for there.

But I'm willing to say it was the first time — but not for sure!

I will watch on and test also for this situation

I've been working on some villagers over the past few days, and the world was recently moved to a realm. Within 2 days of the realm being online, 6/7 villagers across multiple chunks have disappeared, which to me shows that realms exaggerates the issue as previously discussed.

I started a new ‘test’ world in my realm as the old one had missing mob issues. Everything ok for around a week. So this morning, I noticed a bunch of mobs had disappeared from my realm; sheep, turtles, lamas, even zombies and skeletons seemed in short supply compared to when I saved and quit the previous night - it was noticeable. I checked the backups and my world was smaller this morning than it was last night. Worlds normally grow in size not shrink. This reduction in size supports the theory that something is happening during save/load or while the world is not in use. I’m going to revert to the largest backup and see if it happens again.

migrated 2021-07-27T07:02:44Z

I honestly think they have no idea how to fix this. It's happened 3 times in a big way to my trading hall. I've lost around 30 villagers with job, names and locked in trades. I've now built a made a 1 chunk holding area and filled it with beds and jobs. I've bred a large amount of villagers in there to see if the chunk border issue is the reason. It's been 5 days and they all seem to still be there. If moajang claim its to do with villagers crossing chunk borders then whts the point of having villagers with legs. The game is hella bugged, even more so on realms. Good luck with your game.

Currently, my kids' and my realm has lost a cured villager, 2 axolotls, 2 iron golems, 3 active minecarts with hoppers, and 5 tamed horses. Then we have discovered hostile mobs had spawned in the location where some of our created or tamed mobs disappeared. The locations were inside our houses, which are very well lit with many torches or lanterns. None of these areas cross chunk borders, and are all on the same large map. This issue has been spread out between 3 different locations on the map, and seems to happen when signing into the realm in the same area. Last night, my minecarts and one golem were there. Today, I ran into a zombie in my highly lit and secured courtyard where the golem was.

I've been having this happen for a few weeks now, mostly with horses and villagers (though also cows, sheep, llamas and axolotls I've interacted with somehow). The other day, I had a horse disappear right out from under me!

I have a video here of it.

I suspect it might?? be something having to do with the chunk borders, so I'm gonna play around with those and see what happens!

GoldenHelmet 2021-07-29T13:05:01Z

V Striker: the issue with horses disappearing when you cross a river or dismount is tracked at MCPE-108568. Fortunately, that one is already fixed in the latest beta.

I think it is due to a desync where the client is not updating the server about the horse’s position, so when you dismount the horse “teleports” back to the coordinates where you mounted it. It may also happen when you move far enough that the horse’s starting coordinates are outside of render or simulation distance. In your video, it looks like the disappearance happens after moving about 10-12 chunks on the Z axis.

@Charles Bohall

I think you might be onto something by noting it happens while signing into the realm. I lost many villagers when my base (where I login and log out most often) was within 3-5 chunks of the village center. When I moved my base either into the village (so the villagers are within 1-2 chunks of me) or far away from the village (so the villagers are MANY chunks away when I login), the number of villagers disappearing dropped dramatically. This was particularly bad while playing on iOS where the chunk simulation distance is locked at 4.

Based on this, I believe one root cause of disappearances is partially loaded chunks as noted elsewhere in this thread.

Returning to your note about it happening while signing into the realm. I’ve noticed with audio on that I sometimes hear mob sounds and can even get attacked during the last few seconds of the “Generating world” screen. This tells me that my chunk and perhaps the ones immediately adjacent are at least partially loaded, even though I can visibly see them load when I can finally see my world and react.

I wonder if it’s during this partially loaded period that villagers and mobs pathfind across chunks borders — even ones blocked by walls, because the walls haven’t loaded — and disappear.

@Evon Silvia

My 2 prime locations are close to villages, but not close enough to be affected by them. I can kill pillager scouts without summoning a raid, and villagers don't know where my locations is. The villagers I do have were cured zombie villagers that I captured from my mushroom farms under ground. The are stored in an underground room with their jobs and beds behind an iron door and a fence to keep them in, safe, and secure. If they are getting out because of a rendering issue, they're walking right into the walls, and dying as soon as the blocks render. All I can say is, ouch!

In regards to my horses, I can barely keep them. In fact, after I posted yesterday, I lost three more, including my best horse, which was a speedy high jumper. The horses have been an issue since the start of the our realm a couple of months ago; however it appears to be getting worse. All the horses in the wild are also gone. All I see in the areas where horses normally populate are abandoned traveler llamas when I search.

Lastly, I've lost two iron golems and four hopper minecarts. I spent a ton of iron resources making this to keep the inside of my castle secure, and to collect dropped items from my bee and sheep farms. When I signed out, they were there. When I sign back in, they were gone. On top of that, one of the golems was replaced by a zombie, which makes no sense to me unless the rendering idea is also letting them in. That could also explain how a creeper got into my fortified and well lit house tonight, and blew a hole in my floor.

Currently, I'm rendering at a full eight chunks to ensure things work properly. What am I missing?

migrated 2021-08-02T19:55:06Z

I think we may be on to something after reading previous comments about partial chunk loading. Because of the way chunks are loaded in Bedrock I believe the chunks may not load sequentially in explored areas - this can be seen with longer render distances - I think the problem may be less with the chunk borders themselves and more an inconsistency with loading order and the seemingly constant auto-save. Will be doing some more tests with this!

migrated 2021-08-07T21:42:36Z

Can confirm persistence of this issue affecting villagers on 1.17.20.30 : two worlds generated thereon and one old one(made on 1.17.10.23 beta) opened, at least 2 villages per world tested (2 on one, 3 on two).

The despawning only begins after I have interacted with the villagers - I arrive at a populated village, trade/check trades, go back to my base and later return to an abandoned village or one with one villager left.

I've excluded the following as causes:

Player occupying villager beds
Village "reputation" issues, eg. hitting villagers, griefing village, etc. (I even avoided any looting from the village boxes on my visits)

Even just paying a short trading visit seems sufficient to start the decline in population.

migrated 2021-08-16T19:04:56Z

So here's a different use case than I knew before. Previous mob despawns seemed to have no connection to any sort of crash. This one is only... almost a crash, I guess?

Anyway, was copying a world on my Switch. World copy failed, repeatedly, at 40%. When I logged back in, 3 named and levelled villagers were gone (already replaced with new child villagers by the time I saw it, though it wasn't more than a few minutes.

This bug literally is the reason I won't spend any money on Minecraft anymore. My kids want a family realm, but this is game breaking. And it really really sucks that Mojang refuses make it a "Mojang Priority."

migrated 2021-08-16T19:19:02Z

Playing on a Realm with 4 other people for about a year now.

All of us had named horses, and over the course of a few months they have just popped out of existence one by one in various areas of the map. Can be there, and then within 5 minutes they just pop out of existence.

At one point, we even had an entire farm of animals decimated overnight without any hostile mobs attacking them - well lit and penned in.

This is a really, really annoying issue, and it's borderline impossible to mitigate. We actually pay an ongoing cost for a server, and the fact we can't rely on the game to correctly maintain things like this (plus it's been ongoing for at least a year), it's almost impossible to remember to tie up your horse on a divisible number of blocks (because you can't easily identify chunk borders) and we can't switch to Java Edition because half of us play on PS4/PS5, one on Xbox and two on Windows. 😞

GoldenHelmet 2021-08-17T02:52:13Z

Eric J Ehlers: Mojang does not use the "Mojang Priority" field in the Bedrock project, so you will not find it on any MCPE ticket. What can see, instead, is the ADO field. Numbers there mean Mojang is tracking the issue internally.

migrated 2021-08-17T12:44:39Z

What does "ADO" mean? there's a severe lack of good documentation about the bug process and field meanings, esp if Bedrock is working differently than java, et al.

ADO stands for Azure Dev Ops. It is basically an internal system they use to track and discuss issues internally. The numbers refer to ticket ids in their system. Since it can contain sensitive information, the system is only accessible to Mojang or Microsoft Employees.

Just lost an "entity" in my 1.17.11 Realm world. I´m using an addon named "Old Style Ferry", by creator @ivon852, wich adds two new entities (small ferry boat and large ferry boat). It works perfectly in all versions and devices, no glitches so far. But last night I saved the world while riding the boat, and when I logged back today, the boat just disappeared, leaving me floating in the middle of the ocean. As these ferries have a chest included, like a llama or donkey, lost all the itens stored in it. Restored from the backup and tried to save and log back again, and this time nothing happened. Lost some 2 hours of playing because of that.

I would like to verify if I saved near or over a chunk border, but I don't know how to check those in Bedrock. This issue's description recommends to prevent entities to cross chunk borders when saving, but how? Do I need to install one Mojang official addon or tool for that?

Edit: thanks, @GoldenHelmet!

migrated 2021-09-06T20:12:33Z

We’re all of a sudden rapidly losing named villagers out of our village in our bedrock 1.17.11 realm. They are cured zombie villagers that we re-homed in an underwater dome village, so they have limited wandering distance and we have consistently interacted with them and nametagged them. Sometimes they vanish while we are not far away mining or traveling, sometimes they vanish between log-ons to the realm. Definitely enough bells, beds, farmers, etc. to sustain the village, and the dome is entirely lit so no mobs are killing them. And they seem to be weirdly linked to their job blocks after vanishing, so if we breed new villagers, the job blocks have to be picked up and reset for new jobless villagers to link to them. Farm animals meet the same fate and just vanish, which sucks because we really like the technicolor jeb_ dreamsheep.

migrated 2021-09-06T23:07:23Z

The job block connection is interesting. I'm not sure it would be helpful fixing the bug, but it does seem to indicate that not all the data is removed. The entity... still exists somewhere.

Reply from @unknown:

The game stores village data separate from entities. Villages check regularly to see if their dwellers are still present. When a villager goes missing the village keeps checking for it for 20 minutes before releasing the link between that villager’s ID and its workstation, bed, and bell. This prevents immediate loss of links and breeding for an empty bed if a villager is outside the village or in unloaded chunks for a brief period of time. The same applies to cats and iron golems, too. After the 20 minute timer expires the village will also check the villager’s last known position if it is in an unloaded chunk, before removing the villager from the dwellers list.

Since the recent update I am having some serious despawning problems with my animals. I was especially disappointed to lose my horses as some were named and 3 of the named were my first horses. They had escaped but I found them weeks later and was able to capture and lead them home, only to lose them through despawning. I have changed the size of their pens; moved the pens and even brought one of them (horse) into the house. The pens have both food and water. It's become a very frustrating situation.

I run a bedrock server , and since the 1.17 update we have had entities despawning.
First instance was a Chicken cooker farm, 20 chickens were nametagged and led to top containing area where eggs are collected.

server command stop to shutdown the server.

Bedrockserver.exe ran to start a new instance of the server.

Upon logging in the chickens are gone and cooked chicken can be found in bottom collection chest.

Server upgraded to recent release 1.17.11.01

within 1 chunk, 8 individual sheep shearing farms were set up.

Sheeps were name tagged and colored.

server command stop to shutdown the server.

Bedrockserver.exe ran to start a new instance of the server.

Upon logging in three of the eight sheeps are gone and cooked mutton can be found in bottom collection chest with the wool.

Admin in creative mode, respawned sheep, re colored, renamed tagged, so entities was back up to 8, same server restart and was able to reproduce the issue.

update 09/16/2021

after servers had issue connecting to Microsoft account services, and services were restored more of the sheep were killed/despawned with cooked mutton in chest.

Reply from @unknown: it sounds like your sheep may be getting struck by lightning, perhaps only on server restart. That sounds like both MCPE-121688 (lightning strikes through blocks) and MCPE-81913 (lightning not showing effects until world reload). It may be a BDS-specific combination of the two, i.e. lightning is not registering on the server until restart, and you have multiple lightning strikes following the pattern of MCPE-121688 stacked up. The storms may also be unnoticed due to MCPE-131325. Could you make a ticket for this in the BDS project?

Yay! New experience! Several incidents since my last comment, but this one was weirder than most. Sorry for the length, but I'm a story teller, and I promise I tried to keep it only to facts directly relevant.

Set up: I have three bases in a single player, local world.

1 next to my original spawn point. This is currently where all my animals are kept. At the time of this incident, probably 2 dozen chickens, 40 or 50 rabbits, 3 horses (with armor and saddles), 4 llamas, 3 donkeys (with saddles and chests), a dozen cats (all named and "sitting" so stationary), 2 dogs (stationary), 3 parrots (named and stationary). Immediately next to the base is a village I constructed that houses 21 villagers, all of whom have been named and traded with to at least level 2. The village is surrounded by a fence, so they can't move too far off and only spiders can get in (extremely rare) plus generally 2 golems spawned automatically (they seem to despawn and respawn with startling regularity. Also some crops, bc convenient.

2 is where I'm working my big project ~200 blocks away on z axis, maybe 300 on x axis. It's a lot of construction, and even more materials. Other than a minecart and 8 or so chickens created by throwing eggs, no entities that I expect to be there from time to time, just a disturbing number of llamas abandoned after their wandering trader was either killed by mobs or (more likely) despawned.

3 is a minor base camp roughly 2000 blocks z axis away from the big project. It has a single entity, a dog. This camp exists bc his world was created before Caves and Cliffs release, which means every place I had visited previous to the release would have no copper (or other new materials). It's where I go to gather copper or amethyst.

I have a current need for a lot of copper, so I was visiting the basecamp frequently over many play sessions of perhaps 2 hours average length, I did not track time, but there were several visits, each time starting a new strip mine tunnel (one direction, so a few hundred blocks at a stretch) with enough time strip mining to fill up a couple shulker boxes (I mine EVERY ore out of habit), then return to main project (2) to smelt the ore and sort all the minerals and drops found. Most of these visits include a short visit to the village (1).

During my last three visits I made an exception to the new tunnel and kept on the same one. In addition to exploring a mine I bumped into, the tunnel ended up being maybe 2000 blocks long, all going further away from all three bases. Nothing unusual after the first 2 trips, but after the third trip, I do my usual smelting and sorting at base project (2). I made a building using maybe 120 blocks (pretty small, considering one of my structures at this base is literally an artificial mountain). Then a visit to the village (1).

At this point the village is EMPTY of villagers. In addition nearly all my livestock, including the rabbits, AND all the indoor pets are just... gone. Literally, there are now something like 4 chickens and a sheep at this villages.

MOST curiously, however, I come to this now empty village and for the first time ever, CATS have spawned. At least 3 cats (they are not my cats, as they do not have names or collars and run from me). I thought that cats spawned based on the population of the village. I reckoned previously they hadn't spawned due to the relative proximity of my tamed cats, but that's just a guess.

Also probably relevant: It has been suggest that a combination of distance and time from the village/base (1) is the cause for this. I find this unlikely. The first village I cultivated, a few hundred blocks further from my mining (and on the far side of the village from it, making the lost village, now provisionally named Roanoke) still has it's entirely population, which is also around 20 villagers, a few cats, and a golem.

There were no system crashes, though I did, at least a few times, save and quit moments after going into the world because I discovered I needed to leave the screen for several minutes and was not in a safe spot.

This was all single player, local play. travel distance is discussed above. Player spawn point changes frequently, as each visit to a base usually includes a visit to a bed, mostly to not have to mess with phantoms. I cannot recall any times where I placed a bed, created a spawn point, and then picked up the bed again. There was most certainly lag at times, bc the world is 250mb and the switch takes a long time to do it's excessively frequent saves, wherein rendering often doesn't happen at all. This lag is always during game load or during fast travel (not something that happens when mining). Travel between bases takes less than a minute due to my system of mine tracks and nether portals.

TL;DR or for those who want a victim count, I lost 21 villagers, 3 armored horses, 2 back donkeys, 4 llamas, a couple dozen chickens, several dozen rabbits, 2 pigs, 2 cows, 3 birds, 2 dogs, and 12 cats in one fell swoop. More distant villages unaffected. Village population based spawn behavior still observed at empty village.

Note from @unknown: the cats spawned because the game still considers missing villagers to be part of the village population until their 20 minute timer runs out. The missing tamed cats probably had been blocking cat spawns before the snap.

Gamershy 2021-09-25T17:45:10Z

Okay so, I don't know how much water this will hold, but I have a strong idea as to WHY this bug happens, and for HOW the despawn can be understood.

It's already been established that the primary problem with entities being randomly deleted from existence can be traced to chunk borders.
To my knowledge, when the game saves chunks, it doesn't do so in a massive lump. It saves each chunk one at time, validates the data, then moves on. To us, this is unnoticeable, and it happens so quickly that it seems negligible, but in this case, it's not. Something I've noticed when just sight-seeing in my world is that far away entities do NOT move smoothly from one point to another, rather, they "teleport" between what appear to be pathfinding checkpoints to reach their destination, often skipping 2-3 blocks at a time. This is likely a method of resource management as the game doesn't need to calculate precise movement for the entity, but rather just roughly moves them to where they want to go.
So, let's build a scenario that would likely recreate this bug:

Most players that visit villages only spend a small amount of time in one, just to do some trading or raiding. So we can safely assume the village is going to be either at the edge of sim distance, or be unloaded while villagers are still moving. If my assumption that chunks are saved one at a time, validated, then moved on is true, then we can see where an issue can lie. Let's say a villager is standing in chunk B. Chunk A is next to it, currently being saved. Now, the villager- while Chunk A is still being saved, decides it wants to move to some block that's within Chunk A. The villager is ignored in Chunk A, as the save already occurred. Now, Chunk B is being saved, and as "luck" would have it, the villager is already in Chunk A. This means there's no villager to be saved to Chunk B. Now, suddenly, a villager that VERY obviously already exists is not saved in either of the chunks it occupied. So the next time the villager is unloaded, it no longer exists when you come back, as neither of the chunks saved the villager. This can also happen when the villager is close to you, but obviously would require more precision to occur. Saves also occur when chunks are unloaded, so if a villager was crossing a chunk boundary at around the same time that the chunk is unloaded, the same issue can occur under the right circumstances, especially if the villager leaves sim distance (chunks are not unloaded all at once, but similarly to how they're saved- one at time)

As for a solution? Don't save entities with chunk data, or at least, prioritize all loaded (or known unloaded) entities to be saved FIRST, before the blocks of the chunk data.
What this would mean is when the game initiates a save all entities are saved internally, possibly to ram, to create a sort of "snapshot" of the entities' positions. Then, when chunk data begins to be saved, any checks to save entities call for the snapshotted positions as opposed to the true positions. This means that even if a villager crosses a chunk border at the same time that the game swaps to save the chunks as described in the scenario, it'd have no effect on where the villager will be saved. The only potential issue this could introduce is mobs being in slightly different positions than when you left, which would likely be unperceivable. In theory, this would entirely solve mobs being despawned at chunk borders.

This whole thing could also explain the random disappearances when you consider the teleporting movement when entities are far from the player.

I have been playing a survival world on my ipad pro for 2+ yrs now. I updated to 1.17.30 and noticed extreme lag to the point of not being able to move for seconds at a time. Each time the lag happened my game’s autosave icon appeared. After it was done I would slowly be able to resume normal movement again. I couldn’t pinpoint what was causing it but it happened each time I turned and faced my mansion. I then realised my 18 armor stands, 2 dogs, 4 cats and 5 horses were just gone. I then suffered more lag as I turned toward my iron farm which I had just come from and when I got in there, found that I only had 4 of 22 villagers left. Each time extreme lag, which initiated autosave, then mobs and entities just gone. All within about 60 blocks. I did not travel away or go to the nether. I was horrified that my hard work was just disappearing almost in front of my eyes that I just quit the game. I luckily backed up my world before I updated and will not play again until this is fixed.

I had a similar issue on my single player world, however I didn’t leave the area or change the mobs’ positions since before this began happening. Also, in the case of villagers, their other mechanics aside from spawning and despawning aren’t working properly. Particularly, the villagers I cure from zombie spawners are permanently locked to their trades and profession by default, (again, this didn’t happen before the last update)

migrated 2021-09-26T22:44:35Z

I too just had a similar experience on Bedrock (Nintendo Switch) since updating to 1.17.30. I didn't leave the area or go to another chunk and after saving and resuming the game the next day, all of the passive mob animals that I had in my barn and castle despawned (cows, sheep, horses, donkey and many chickens). I immediately tried to corral some new animals and those too disappeared. After a few more tries, it seems the animals are staying around for now.. This is the first time this has happened and like everyone else, I assume this is related to the update.

Experiencing similar despawn issues on a Win10 single player survival world after updating to 1.17.30. Numerous farm animals disappeared as well as a master librarian. It might be related to chunk boundaries as the pens which appear to be fully inside of a single chunk are not missing any animals, but the pens that span chunks are missing animals. The villager shared a house with another master librarian which also spans several chunks.

I have experienced this as well. I was playing in single player PE (iPad) and logged out. The next day I reloaded and all my villagers and cat were gone. They only stay within a small area and this has never happened with mobs before. I have had an incident where I reloaded and my inventory was wiped. I am unsure about chunks since I’m on iPad and don’t know how to or it isn’t a part of this platform. This was just the other day so it is V1.17.30.

I'm playing on a realm , on Android (redmi 7a) , while coming out of a nether portal army base , if the chunks don't load in time , the hopper minecart in my melon and pumpkin farm randomly disappears , I've replaced it 3 times , however flying away by elytra does not unload it at all

I lost about 30 bees to this bug (at least it seems the most likely explanation). This was on Xbox Series X with Simulation Distance set to 8 (back in 1.16). I had a little farm set up with 10 bee's nests and some flowers they could pollinate. The bees were fine for weeks, until I went to work on a big build that was about 8 to 10 chunks away. I worked on that build for many hours, not realizing that the bee's nests would be barely within simulation distance depending on which part of the build I was working on. When I came back to the base, every bee had vanished except for one. The one remaining bee was trapped in a 1x1x1 space where it could not move (there are blocks above and below and blocks or slabs on the sides preventing it from moving). I searched the area and the lost bees were nowhere to be found.

The bees that vanished had been free to fly around their nests and there was a chunk border they could freely cross. This disappearance is consistent with the bees vanishing when they tried to fly from a loaded chunk into an unloaded chunk. Additionally, the one bee that was stuck in a tiny 1x1 area still hasn't despawned despite my continuing to work on that nearby build and others at a similar distance for many months up until today (in every version up to 1.17.30).

I experienced this bug repeatedly with a hopper minecart in 1.14 on the Xbox One S. I had a large sugar cane farm that used 6 different hopper mine carts. One of the 6 had a track that crossed a chunk border and the other 5 did not. The hooper minecart whose path crossed the chunk border disappeared, was replaced, and disappeared again. None of the others ever did. After 5 or 6 times, I modified the track so that it no longer crossed the chunk border and the hopper minecart did not ever disappear after that.

I believe this w world was on Sim 6 or 8, and either way I was moving around the area in and out of simulation distance to the hopper minecart working on different projects when the disappearances happened.

With all the focus on chunk borders, I wanted to point out especially to new commenters that among the hundreds of reports on this problem several mention sitting cats or wolves being lost. Crossing a chunk border during the save process is certainly one reasonable explanation for disappearing entities, but it can't be the only reason. As well, any cause which is not related to chunk borders could explain every other occurrence whereas "crossing chunk borders" can only explain some of them. Frankly after watching this issue evolve over 4+ years I think the issue is a more generic chunk saving problem, not specifically related to "entity crosses a border at the wrong time". I'm not convinced the borders really matter so much (not that me being convinced matters at all). The good ❓ news is that it seems to be happening so frequently now with 1.17.30 that it ought to be fairly easily repeatable by developers. Fingers crossed. All new commenters please vote for this issue, thanks.

I've been working on an enormous castle/village for weeks on solo survival.

I spent some time a few chunks away from it to build an iron farm, and when I came back to my castle, everything was gone.

I had a stable with over 30 saddled/armored horses enclosed, my entire farm of pigs, cows, sheep, llamas... Every dog, every cat, every ocelot and golem, sitting, roaming or tethered...

I had an armory with 36 armor stands, much of it with fully enchanted diamond or netherite armor...

All of it just vanished...

I'm now faced with the decision to go back to my last backup of the world and lose a weeks' progress, or go back and spend countless hours getting all those animals/materials back...

Just noticed I´ve lost 2 named and fed axolotls, wich were kept in an underground aquarium, full of water, made of glass and glazed terracota blocks, with sand floor and one wood trapdoor for access. Its dimensions are 4x4, it is totally contained in a chunk, and it is underground (4 blocks below sea level). The Axolotls lasted for almost 2 months there.

I've had cases where I would go in the ocean and the drowned with tridents would kill me. When I would come back to get my stuff (even setting the spawn point to the nearest beach), the drowned that killed me would despawn. The trip would take like 10 to 20 seconds. It's not normal!

What I was doing prior to entities disappearing: Before armor stands with armor, and paintings, disappeared I had been based near 2091 73 -3605 using a portal that came out at Nether coordinates 342 60 -459. I was in the Nether for over an hour, and died several times to respawn at 2100 65 -3657. When I returned the regular way I ended up at an overworld portal near 2774 63 -3584. From there I teleported back to 120 64 -24, my base.

Single player/Nintendo switch

Despawns were near one of my base spawn points. I had changed spawn point from 2100 65 -3657. Paintings in a nearby village were not affected.

I had been experiencing despawning of pets and villagers (even those with name tags) persistently, but not more frequently.

I had this happen a couple of weeks ago when I went to fight The Wither in The End. I thought it had something to do with all the portals. But it happened again today and I think it might be related to something else.

What you were doing leading up to the mobs disappearing?

Today I was within 2 chunks of a cat, 2 chickens, 3 minecarts, and about a dozen sheep that disappeared, building the start of a wool farm inside my base. I don't know precisely when they disappeared because of how the day went.

The minecarts confuse me the most. I specifically built the farms they're related to inside one chunk so this wouldn't happen. They disappeared anyway.

After the first disaster, I've been making copies of my world every morning. But that's the interesting part. At lunch, I made a copy of the world and made that copy Creative so I could try out a few different placements of wool farm modules. This evening I worked in that copy for about an hour. I never really left the same 4 or 5 chunks, it's all inside my base so all my stuff was there. After I'd figured out how I wanted to start my farm, I quit and loaded the Survival world. That's when I noticed everything was gone.

I think this has something to do with copying files. I hadn't played the specific file where everything disappeared yet at all today, I only made a copy of it at lunch. The last time I had things disappear, it was immediately after I made a copy of the world, then loaded. In that case I did some Nether travel to about 1,800 blocks away, saved, made a copy, then went into The End, fought The Wither, and warped back. Neither the original file nor the copy had my pets.

single vs. multiplayer, local vs server/realm

Single player, Switch version

how far you traveled

The first time, about 1,800 blocks. This time, fewer than 40 blocks.

how long the current or previous play session lasted

About an hour.

whether the despawns were near a player spawn point or if you had changed your player spawn point during the session,

Yes, everything that has disappeared was within 50 blocks of my spawn point both times.

if you experienced lag or anything else abnormal.

Nope, the only abnormal thing is having pretty much every entity within 3-4 chunks of my spawn point despawn, even named and tamed creatures and minecarts with hoppers.

Appears as if all the other disappearing issues are being linked to this... so I'll comment here.

Occurred Oct 2nd, 2021:

Had an Armor Stand with full set of enchanted diamond armor disappear from storage room, in Minecraft Bedrock on Nintendo Switch. No system crashes to speak of. Armor Stand was approximately 20 blocks away from bed/respawn point. I had previously travelled approximately 250 blocks away at one point, and into a cave. Armor Stand was stored in a closed room and had been used/interacted with. Game is not on Realms, single player only. Hopefully gets sorted, kids don't care to play it anymore if they are going to lose stuff due to bug.

Don’t know exactly when it happened. All i can remember is it happened sometime close to the time i got on. When i discovered it was when i was going to trade with villagers and all the stalls with villagers were empty then i looked for my cats and so on. Previously the bug would take villagers from chunks. This happened before 1.17.30, the mass despawning happened after.

SirDaddicus 2021-10-05T17:25:33Z

I tried a "fix" for villagers in three worlds: vanilla 1.17.1, 1.17.1 with C&C datapacks, and 1.18. In all three cases, I built a wall around my village at exactly the chunk boundaries (i.e. in the first block of the four neighboring chunks).

In all three cases, I have not had a single villager disappear randomly. So, for villagers, this might be a decent workaround.

Hi, I have lost 3 Villagers in my Bedrock Server. I have been going in between my trading hall and my base, which is about 200 blocks away. The trading hall is at Y-17, just above a zombie spawner. The villagers can walk in a 15 by 15 which is located in a chunk. Beds are located 1-5 blocks outside of the chunk while workstations are inside of the chunk and the villagers can not get to the beds. I have been confused because I have had villager trading halls in other servers/world in pre=1.17.30 and as long as they are in chunk borders that villagers have been fine.

@Mods, Helpers and QA Team: maybe you could address this issue's description more globally, because we already have evidence that it occurs with any mob and entity possible, in any situation (crossing chunk borders or not, named or interacted in any form), and it got even worse after 1.17.11 for some reason.

For the players, I would recommend making backups often, and checking your valuable entities for missing ones when possible.

Reply from @unknown: I don't see how the report description could be any more global than it already is.

Hi, I lost 45+ villagers on my trading hall plus animals on my breeding chambers.

As per questions listed:

I built a full chunk 16x16 pumpkin farm 2 chunks beside it with 100+ pistons and observers with hopper cart(hopper cart vanished when bug happened)
Single player
About 2 chunks away
Last i saw my villagers was 30mins session
Near spawn point
I experienced Lag when opening trades, chest and save lags for at least 1-3 mins within the bug area(sometimes it pops up connection error after saves) That generally started after i almost finished my trading hall.
one more thing is i don't remember correctly if i Save&Quit or i just left the console on auto off
I play on Nintendo switch Minecraft Bedrock
World data is 96-101mb
Active texture pack is default

A little info:

Villager trading hall is on a 16x32 building.
Villagers cannot move
Inside 4 chunks
I crammed farms(Pumpkin, Tree, bonemeal, cow, seaweed) in a little area. These are where there are occasional lags.
Farther is an Iron farm, Mob farm and Villager breeding farm which is still working.(around 100+ blocks away from Trading hall)

The bug:

45+ Villagers disappeared
2 Zombie villager and one Zombie on cart disppeared
surrounding area 4chunks and 6 chunks away, animal mobs farm despawned
All surrounding hopper minecarts despawned.

@Goldenhelmet – there does seem to be a misconception that chunk borders are "the thing" – perhaps because the "workaround" is posted so prominently. But with so many cases of immobile entities (horses in stalls, villagers in a trade hall, etc) – this seems to be a misleading workaround. It's clear many of the users are focusing on that specific cause, though. Perhaps either demphasizing the 2020 workaround, or at least more strongly wording the info in the workaround that it is not intended to be a fix for all situations, and only may help some situations. Though, to be honest, that is explicitly stated in bold text already, so... people just gonna read what they want to see, I guess.

I have had a few minor losses recently that involve lag (world is now > 290 MB, the Switch takes some time to render when it's saving) but not crashes (I've not had Minecraft crash or close without a full save in quite a while). Nothing on the scale of "roanoke" that I mentioned above, but a pig or a cow here and there. Most recently it was a pig and a cow – both babies – while the other four cows and four pigs were unaffected. All 10 animals were in the same pen which probably crossed chunks. The disappearance happened after a 3ish hour play session. I did close/save and when I rejoined the next day the babies were gone. (only listing mobs because the baby - parent connection may, somehow, be connected?). I have lost child villagers one or 2 at a time this way in the recent past as well.

migrated 2021-10-08T16:49:31Z

I know it's confirmed for 1.17.34, unfortunately, but I had to verify it myself... well, verified. I have a test world (a copy of my own play world) in slot #2 of Realms, prepared with some interacted mobs kept in pens (chicken, villagers, axolotl, etc). This world is 64MB. Made a quick trip to a far village, 1800 blocks afar, slept there and returned to my base. Just one chicken was missing.

As no one here in the comments reported confirmation for 1.17.34, but this version still was listed for the issue, I presume the QA team finally have a test world with the conditions to reproduce the bug whenever they want. So, this is good news (if I'm correct 🙂).

migrated 2021-10-08T18:46:25Z

Could the cause of this issue be the very long game sessions?

I started seeing this problem in my world after I afk for awhile at my iron farm. I had all my trading villagers despawning, there were about 200 blocks away from the iron farm. Interestingly, the cats in the trading hall didn't despawn, but other pets, and horses with saddles, around my base did!. After that, all villagers from the iron farm despawn as well.

migrated 2021-10-09T07:09:08Z

I had npcs, standing still (not crossing the chunk border) disapear simply upon reentering a world. Yh same goes for armor stands. It also seems to only happen at about a fifty block radius of the original spawn area.

Also, it only occurs if you exit the world without pressing sve and exit.

migrated 2021-10-10T09:46:51Z

Well, I was /told/ to put my info here, even though it seems like a different bug to the original, so I'll do it.

I had a pair of a tethered horse and donkey completely disappear, when they were tethered to the same fencepost. They were tamed, but not named, or given armor/chests (thankfully).

I also had one of a pair of tethered horses that were tamed, named, armored and saddled completely disappear. They were again tied to the same fence but only one disappeared. However, their child that was freeroaming in the same small pen did not despawn, and no mobs I've left in pens that are not tethered have despawned, so I do not believe it's a chunk border issue, but one with the leads.

(It may be linked to crashes, as I found the second one missing directly after a realms crash (which, really, shouldn't happen, I'm not even using intensive redstone or making any lag) but I can't say for the first two since they weren't my personal horses so I didn't notice it immediately.)

HairBand1980 2021-10-10T14:35:54Z

My issue was closed as a duplicate of this, although I believe they are different issues. I have been experiencing the issue of this report here since 1.17, but when I updated to 1.17.34, it went nuclear. I lost literally every entity except one named villager. Dozens of cows in a pen, gone. Dozens of sheep in another pen, gone. Chickens in another pen, gone. Horses, gone. Pet cats, gone. Cured villagers, gone. Minecarts with hoppers, gone.

I went to start replacing the livestock, first. Penned a cow, decided to test whether it saved. Using the app on iOS, in all the years I’ve been playing, I’ve only ever had to close the app for everything to save. This time, I close the app, and reenter to an empty pen. So I corralled another cow (three in a group this time) and put then in a pen. Tried Save & Quit instead of just exiting the app, then reentered, and the cows were still there. After having saved them through these means, I again quit the game by closing the app. Reentering, the cows, previously saved, are gone.

This is disastrous. I spent countless hours arranging and corralling these entities, and it’s all wiped out. And even if I rebuild it all, now I can’t even depend on them being there because it will only take one instance of the app being (accidentally) closed to wipe everything out again.

Please review and reopen MCPE-144208. It is almost certainly an new and different issue than this one.

UPDATE: And now my one named villager who was sleeping in a bed has disappeared when it turned daytime. Also, my named skeleton horse. It is now literally every single entity gone. Hell this is disheartening.

When a chunk is not loaded with a trident killer the trident de spawn

migrated 2021-10-11T02:42:16Z

I don't think the bug is despawning entities directly. In my world, just under my village (where my billagers have been despawning) is a cave system full of my villagers. I think the recent updates are loading entities in slightly before the blocks they're standing on, and they are falling into the ground below. I experienced similar issues with my teleporters in the past. Command blocks with the code: "/execute @p[r=1] ~~~ /tp @s new destination coords" would randomly spawn the player 1 block down of where they were supposed to be, or using the teleport would kill the player. (I'm assuming by suffocation or void).

Furthermore, not only did i find villagers beneath my village, but i found over 10 zombie villagers in a single spot in a well lit area clumped up on eachother that all loaded when the chunk loaded.

So! Unless i missed some massive hole in my village that drops things into a cave (and i assure you there isn't one) I believe the entities are loading before blocks and falling instead of outright dissapearing.

Hope that helps! I created an account just to report this. I have videos on my ps4 but don't know how to add them to this.

(I play on an xbox started realm from my ps4, with experimental gameplay turned on without education edition, and as previously mentioned, command blocks are enabled. My game plays smoothly dispite 5 players on at a time, and runs pretty well.)

migrated 2021-10-11T13:51:25Z

David Robinson - what I do for PS4 videos is upload them to youtube as unlisted, then paste the link in my report. I had been thinking this could be related to the way bedrock loads chunks, so you may be on to something here. I'll do some testing with it and maybe we can come up with something conclusive.

migrated 2021-10-11T16:05:59Z

@David Robinson, your proposed theory is very solid. I even did a test and dug under the place where some of my lost entities were standing, but found nothing in the caves underneath. I've lost some armour stands, but found nothing, even digging until bedrock. I don't know if armour stands can "die" from suffocation, maybe thats the case.

If Minecraft Bedrock had the capability to log specific entities, like Minecraft Java, we should have reached a conclusion by now... My best hope is the Bedrock Dev/QA Team have something like a Developer Version with stronger logging/debugging capablities. Me and my kids stopped playing for 2 months now, just waiting for this bug to be repaired.

migrated 2021-10-11T19:36:14Z

I have lost about two whole villages and also my horse.

Also, there's another bug that can be related ----> Everytime I enter my world without logging, the world goes back to menu and i have to enter the world again. This can be one of the reasons for this desappearing bug, because theres a probability that the world goes back to the menu without saving it first, causing the despawn of entities like horses and villagers

migrated 2021-10-11T20:07:05Z

@David Robinson. How does it feel to give me hope then crush it?! 😃

I tested my village. I dug down to Y 11 in multiple places in Roanoke. Only one of them turned up any open space, and it was mostly water. I think it unlikely that this was the fate of my villagers. Also, Some of my lost animals had open levels I had built below them when they despawned, but they weren't there.

However, due to the fact that chunk restriction seems to help in some cases (but only some) it would seem that there are likely multiple bugs causing this. If the chunk load is responsible for some, and your explanation is responsible for some others, my guess is there are 3+ causes. Which... seems to be a case for refactoring the entire save process, imo. If it were my project and I had this degree of failure with multiple causes, I would be starting from scrap. Probably reuse a lot of functions, but I can't imagine just putting a band aid on it wouldn't cause more bugs and less readable code. It'd be like the kitchen of an Italian restaurant in that repository.

migrated 2021-10-11T21:59:51Z

@@unknown , you're probably right about the 3 causes, because if we look at this page's details, we see this bug has 3 tickets open in ADO (Azure DevOps).

But the team is very secretive about this, I tried contacting Mojang and even some Bedrock devs to nil results... I have a hunch they tied this bug's resolution to the efforts to increase Java parity.

Until it's resolved, our main world with all our entities and mobs is kept safe as a backup file.

migrated 2021-10-12T10:07:15Z

This happened to me yesterday. I'd been spending a few hours working in my castle base, not contiuously as I'd been logging in and out a bit over the evening. The base is at my spawn and I'd been within a couple of hundred blocks of the mobs the entire time. There were a couple of things to note:

The cats and dogs that were made to sit and the llama in a minecart did NOT despawn. Everything else did.
The villagers that despawned were all below Y=64. The ones higher up all made it.

migrated 2021-10-13T03:24:05Z

I play on Xbox. This bug was absolutely catastrophic in our old world. This bug affected it when it was both LAN and a realm. However, this was because my old base was on a chunk border. I only know this was the case because of a previous bug that rendered entire chunks invisible when leaving the nether. I would have mobs despawn not just between saves, but while playing. There was one memorable occasion where I called another player over to show him the new enclosure I had just build for my new pet fox, and when we arrived the fox had despawned. In our new realm, I believe that my entities at my base are unable to leave the chunk they are located in. I have only lost one mob at my base, a villager, and that was after I viewed a clip a friend had sent me and forgot that this causes the game to crash on Xbox. I have had the world unexpectedly disconnect one other time and lost no mobs. However, one of our naturally generated villages is now completely devoid of villagers after being explored once, and I suspect this bug is to blame since it wasn't in render distance of anyone's base so they couldn't have been killed by hostile mobs. I definitely think that this bug is tied to the way that chunks load and save. Either chunks fail to save the entities inside entirely, or they fail to save them when they are mobile or have crossed borders recently. It might be a good idea to check if when this bug occurs with mobs that are unable to move and are located completely within a chunk, if all of the mobs are lost and not just a few.

migrated 2021-10-14T15:58:30Z

So, I've did some experiences and managed to create a reproducible realms test world where 50% of the time I lose mobs, more or less.

It's very simple, just create a 16x16 pen inside a chunk, and fill it up with chickens spawned from breaking eggs. 20 chickens will do. Feed or tag them, and sleep in a chunk near there some days, to replenish the mob cap in the near chunks. Them travel to circa 1000 blocks far, sleep there, and travel back. You'll have lost some of your chickens.

Now it appears to me its related to a defective mob cap algorithm, associated to chunk saving.

In 2 days we will have a Minecraft Live event, and a new friendly or tameable mob will be choosen. I hope this bug is resolved before these new tameable mobs arrive, or this bug will be in the spotlight in no time (just imagine thousands of players losing their favorite allays, glares or copper golems...)

The bug definitely happens on save or load. This afternoon I played for about 2 hours then, as is my protocol because of this bug, I went back to my base and verified my cat, chickens, etc. were there before saving and quitting. The screenshot of the save file has my cat in it. I load the file and it's gone. That's stupid.

When I loaded the save tonight, all of the entities are gone. A cat, 3 minecarts, 2 chickens, 8 sheep, I don't know how many cows, and my patience. I'm getting tired of losing entire afternoons of progress. I'm getting tired of having to make 2 copies of the world before any session. This bug was created 5 years ago, it seems like it should've been fixed!

How am I supposed to get excited about the new mobs? I can't trust them not to be eaten by this bug.

New event that appears different from the majority of my losses.

mandatory on Switch, play session was about an hour before this happened. Single player, local.

I took a horse on a longish journey. 1100-1200 blocks west maybe? died. Respawned near point of origin. Took a second horse to same location. Penned both horses, did my bidness, tamed a couple cats, then headed back riding Horse #2, with Horse #1 on a lead. When I reached Roanoke, I put Horse #1 in a mine cart bc I have a track to my base/spawn point. Pushed him then followed on Horse #1, both cats still following. This is a stretch of ~300-400 blocks south east. More south, but the majority of the track is diagonal.

When I arrived at base, horse #1 and minecart were at the stop point. I went to the stable to deposit horse #2, a move of approximately 10-20 blocks in both X and Y. Went back up to get horse #1, but both it and the minecart were gone. At this point I noticed only one cat was still with me. The start of the mine track has a bed, so I thought it might be there. And I thought maybe the minecart got bumped when I moved the other horse, so I went back to the start of the track. No cart, horse, or cat.

Addendum: I played about another 1.5 hours, mostly messing with my trading hall. I needed another villager so I went to check on my breeders, 100 blocks from the trading hall. Both adults (named farmers, but not traded with) were missing. There was a child villager, however. There is a 9x9 area on which the farmers can move, though I can't guarantee it's within a single block. The child villager entered the stream which I use to transport them automatically to the trading hall, but never arrived at the other end. I went through the stream, and he wasn't there. It is conceivable he could have drowned, but, there's a constant flow. To drown the AI would have to have made him stay in a single block of water source that has a full block of air below it (buttons to keep it out. If he drowned, he was the first in well over 30 villagers to do so. I reckoned he de-spawned like his dear old dads. (They are named Adam and Steve). The breeders were located a good 100 blocks from the spawn point as well.

Extraneous: I'm fascinated by @Tarjei Aasen's report. The Y coord grouping is bizarre. It doesn't match all my experiences (the horse that despawned was at Y63 and the villagers at Y~40, so today's does. But my Roanoke Catastrophe took place at and above Y65. Well, that's not accurate. 6 of the cats were something like, 59, 53, and 47 in the basements. But all the livestock, other cats, birds, dogs, and villagers were all at (at least) Y65. So, assuming the same bug, Y64 might not be anything special, but Y-space grouping is interesting. Isn't a chunk from bedrock to top of the world? Or am I remembering that wrong?

migrated 2021-10-15T15:06:45Z

It might be worth noting that I've experienced this bug in the nether as well. I've had cows and pigs despawn at Y=76, and have had villagers despawn at Y=78

In the hopes of this getting resolved quickly as it is truly the worst bug that could ever happen, this is what happened in my case.

I have 42 villagers, all inside a chunk in a vertical structure (I made sure they were all inside the chunk and not on the border). Everything was fine until about 6 of them simply vanished. Additionally, two minecart hoppers vanished, but these were two chunks over being used by my mob farm. I play in a single player world, (skyblock world (flat world) where the only structure ls are the ones I have built and where mobs don’t spawn (or rarely do) because I have lit everything up). Although I can not say with certainty how the bug or glitch happened, I believe it may have happened when I either left the chunk, or more likely when I travelled through a nether portal located one chunk over from the villagers and when I came back through the same portal some weird visual bugs occurred which I have never experienced before in my many many years playing. Additional information (may or may not be useful, idk): I play on MCPE IOS, latest update, the villagers constantly spawn golems, no major lag source other than villagers themselves, simulation distance of 4, villagers located at around 170 on the vertical, villagers vanished in a random pattern, portal is at 5 on the vertical.

I can clarify on any detail if needed.

In my opinion this bug is as bad and worse than the realm reboots where progress is not saved and lost, because this is significant progress that has been done over multiple days or weeks just to have it vanish. Villagers are a pain and I honestly don’t know how much longer I can stand this bug… it’s the kind of bug that wants to make you quit your world (which I have) and the game.
Hope it is a priority and gets resolved quickly and for good.

I spent several hours building a guardian farm, and quite a few gathering tridents. 50 tridents took me multiple hours to collect using looting 3, sim distance of 4, and a big ocean. I put all the tridents in the trident-killers, left to get more food, and came back to find hours of progress had vanished. I have also lost quite a few at my raid farm.

A NEW PROBLEM: The rates of my mob farms (including iron farms) are negatively impacted. Silentwisper's 1400 iron per hour farm produces no more than 500 iron per hour. I confirmed the issues are not with the village stacking, but the farm only produces one golem at a time.

Just how @Jonathan said, this is just one of many game-breaking glitches that makes me want to give up putting time into Bedrock Edition. I have experienced so many crashes, had my stuff deleted, and had so many hours of my time wasted due to stupid glitches and bugs.

I have had entities and projectiles despawn at ocean level, to nearly Y100. Including but not limited to villagers, tridents, mob drops, hopper minecarts, named hostile and passive mobs, hostile mobs holding items and wearing armor, and more.

Hello, I am new here and I think that I have noteworthy information and hope not to annoy. To get to the point: All villagers (not naturally spawned) disappeared, and my animal farms who were ca. 30 blocks away despawned. My donkey also dispawned very close to the animals, the animals being closer to the village. Before this happened I travelled far away to mine in a mineshaft (more than 800 blocks), then came back and everything was normal. Then in multiplayer, it could have been that I turned standby mode on my Nintendo Switch on before exiting the world. So shortly,t least 100 blocks wide all mobs disappeared. But interestingly, the cats of my village did not despawn. Even though I made some of them "my cats", it seems like they did not "belong" to me anymore, rather to the village. Perhaps "my" cats despawned and the cats of the village did not, or respawned. They are three cats. So, everything except these three cats despawned. My bees who live ca. 100 blocks away from my village and ca. 50 blocks away from my animal farm seem to be reduced heavely. There were more than 10 of them before the bug occuried, and after it happened, they only were 5-7 (I copied the world and destroyed all behives after some time passed, they probably reproduced so they were even less, I put more than 12 beehives, most of them were empty). So shortly, some cats survived the bug, seemingly the cats of a village created by the player only and some bees who seemingly were in their beehives. Hope that helps.

migrated 2021-10-16T12:11:54Z

I've found this other bug that seems somewhat related to our MCPE-21416:

MCPE-141539: Projectiles launched by the player fall through blocks, sometimes into the void, when player moves far away.

Description: Player-launched projectiles, for example tridents in a trident killer, will fall into the void once the chunk is unloaded.

So... tridents and arrows are entities also, right?

Hope this helps in the debugging!

Trading hall: all villagers lost

I build a 6-portal zombie piglin xp farm, each portal 15x15. The build didn’t make them disappear, but after using it for the first time, for maybe an hour straight, they were gone. I had one crash while afk farming, and constant ~5 fps. But I let the device be and just listend to an audiobook while afk farming.

Single player
The xp farm is directly besides the trading hall, maybe 10 blocks apart from the closest parts of each
Mayyybe a week
Yes I changed it many times, sometimes while traveling, sometimes at the place of both structures. Sometimes I slept in the villagers beds, cause I couldn’t find mine.
Oh yeah constantly, the trading hall alone cause ~20 fps, but together with the finished so farm (if the portals are on, but the farm isn’t) maybe 15 fps. And while the farm is running see 1.

^{THANK GOODNESS I make daily backups. Remember guys: always make backupS}

^ADDICTION

I loaded up a 1 day old backup and continued from there. I didn’t build the farm yet, I was just gathering the material, and now I noticed 9 out of 22 villagers gone. I did a lot of switching my bed around, sometimes near the villagers, sometimes 100 of blocks away, sometimes in the end, etc.

Hi,

I've had issues with villagers and other mobs disappearing in my world.

I'm on MCPE 1.17.34.02 and had a total of 30 villagers in my iron farm/trading hall which is chunk aligned. All was working well until I died making some changes to it, I respawned and went straight back to the farm to find every villager gone as well as the 2 sheep I was using to get wool for beds. I also had a pillager in a boat not far from the farm and that had despawned as well as the boat it was in although the bees I have in between the villagers and pillager are still there.

I then went to a village (appprox 2000 blocks away) to get 2 more villagers to put in my villager breeder underneath the iron farm and half way back they both despawned when in a leashed boat behind me.

This is all on a single player world, i set my spawn point at the village before collecting the villagers and nothing abnormal happened before any of this occured.

My villagers are disappearing into my world.

My villagers who disappeared was trapped in a place with good lighting and they was tagged with nametags.

The path I took before he disappeared was from my house (which is next to the villagers' place) to the gold farm which is basically about 100 blocks away. I stayed there a whole day and went back to my house to sleep and the next day I went to check on the villagers and one of them disappeared, just the one in a chunk border.

Details:

• World singleplayer

• The world is weighing 57mb

• Rendering distance: 14

• I play on an android device (8gb ram)

I’m no expert on the matter but it appears that nether portals may have a strong connection to the problems being experienced. However the fix cannot simply be not to use nether portals because then the game would no longer be a functional version of the game. Furthermore, these problems remind me of the roll backs happening on realms which seem to be tied to villagers and nether portals. There is a greater overarching problem here that needs to be identified and addressed rapidly before the game continues to deteriorate.
Now I would also like to leave a message to the mods and developers; Agnes said during the Minecraft Live that Minecraft is a game that people can trust, where they can create worlds with amazing creations. This is no longer the case on Bedrock. We can no longer trust in the game because it physically deletes significant portions of our progress. How can the developers be so concerned about assuring people’s existing worlds in the new update are not impacted at all and not seem to care about this issue. The ticket dates back a good while and there has not been any updates recently. Therefore we must assume little is being done to address this serious issue. All we ask is for attention to be brought to this problem and the issue fixed once and for all. If you could please provide us with an update it would be greatly appreciated. Thank you.

I had a well lit, fenced in village about 20 villagers strong, each with their own work station and bed. A couple of cats, sheep, horses, and cows. I was simply building a new house within the border of the village with concrete and deepslate when I saved the game and closed out. I went back in about 10 minutes later and everyone was gone. The amount of time I had been on before I saved and closed was about an hour and I'm in survival mode. This also happened in two other saves as well. Pretty much the same way.

migrated 2021-10-20T07:25:14Z

I have been waiting about a month now for this to be fixed. The bug alot of people are reporting is new, not old, which started with the 1.17 cliffs update. Mobs and entities are not despawning, they are disappearing. It’s not about chunk borders or nether portals either. It definitely seems to involve the saving of the game however. I second the opinion that this needs to be a separate bug report and also agree with Jonathon with no longer being able to trust the game. This needs to be elevated because everyone is losing valuable time and effort.

migrated 2021-10-20T10:57:10Z

I am also having villagers disappear with no apparent cause. This has happened 3 times in the last week. The village is in a Taiga biome but I ship in villagers from other biomes for diversity. Max population is about 21. Disappearances involve various numbers of villagers. The other week it was the whole village including iron golems. Yesterday I lost 3 then 2 more in the same session. Today another 8 vanished. My bees are still present though.

I agree with others that this is becoming a game you can't trust anymore, putting hours of gameplay in and losing much of the progress is quite frustrating.

Now the details.

what you were doing leading up to the mobs disappearing

Building houses, etc within the village boundaries

single vs. multiplayer, local vs server/realm

It happened while playing solo initially. I have since moved the world to realms with only a few other players and it has happened there twice.

how far you traveled

I'm usually within the village boundaries which has about a 70 block radius, so I guess I could be up to 140 blocks away if I'm right up one end the the villagers are up the other.

how long the current or previous play session lasted

Play sessions are usually several hours.

whether the despawns were near a player spawn point or if you had changed your player spawn point during the session,

I sleep in the same bed located within the village, so I don't change my spawn point but this may cause the villager who normally sleeps there to unlink until morning?

if you experienced lag or anything else abnormal.

No lag or errors were noticed.

migrated 2021-10-20T13:41:23Z

It's getting very difficult to refrain from obscenities about you Minecraft. There are definitely going to be daily posts about the lack of progress on the bug.

NEW EVENT YAY! (Why in the #### I'm even still playing is a mystery, this is so screwed up)

Switch, single player, local.

Need a metric ton of nylium. So planning to go to the Nether. I hates the Nether, so I do the closest to cheating I do on my survival world, I make a copy of the world.

Go into the copy, make some progress in the Nether, I hit a mile stone, make a second copy. Now, it appears that Switch has a 1GB limit on saves. As the world is around 300MB, that limits me to 3 copies of this world. I now have

original world
The first copy (same original state, now with progress)
The second copy (same state as first copy's progress)

I load second copy, play a bit and die because of some glorious screw up. I weight the options. I have a bunch of mats (and my elytra) gathered in an ender chest, so could just rebuild armor/gear and go back, or restart at the milestone. As rebuilding the gear will take something like 40ish diamonds and 100ish enchantment levels, I decide it is LESS bother to gather the mats again. I attempt to make a copy, forgetting I already have 3 copies. The copy fails (after like an hour of waiting (hyperbole!) through the hang at 40% it always does) Grumbling, I delete The first copy, bc it's a dup of second copy. And make third copy.

If this were all logic, this leaves an identical set of copies as previously, but with one of them having a different save date/time

I enter third copy, get all the rest of the mats I need (including an accidentally discovered ancient debris! WHEEEE!)

Return to overworld. Hey? What happened here? There are no doggies at my base's cave entrance. Where are Huey, Louie, and The Third One? And where are the 2 as yet unnamed but obediently sitting cats? I venture inside. Where are my four horses with saddles and one with diamond armor? (sadly, they are not Famine, Death, War, and Pestilence, bc that is what I named my pigs). And Shadrach, Meshach, and Abednego the llamas are gone? As is Riker the donkey and the unnamed but beloved mule I bred and raised from a child? GURGI IS MISSING! MY CAT GURGI IS GONE!

Suspicious, I venture to the livestock pen. My 16 multicolored sheep (names will be given on Twitter, but I'll spare you here), the cows Jessie, Bessie, Tessie, and Frank, the pigs (named above) and half a dozen chickens (all from thrown eggs) are not here? It looks lonely.

I check the bees. The bees, (at least some of them) are still there. Whew. That's a bigger pain to replace. Welp, the village is over 100 blocks away, surely they will be untouched. Nope, 32 good men and true gone, all named and traded heavily with, and all de-zombified at least once. As are the 5 named cats. And,.. uh.... the named and penned zombies I have to keep them in line and highly discounted (Thelma and Louise, if you must know).

There was only basic lag that comes from travelling on an elytra with fireworks through a dense area like the Nether. No crashes. Departure to the Nether was within 100 blocks of the missing animals (but, as said, not so close to the village). Egress is further away due to multiple Nether portals close together in the Overworld (original gate was next to Roanoke).

I close and save copy 3, and try to decide what's a bigger burden, regathering the materials or rebuilding all the mobs? Well, lets see where we are. Check Copy 1 (progress after first copy of the day), which is in the nether. It takes a few minutes to get out, but I dont' worry about preserving much bc I just want to know. Nope. All gone.

Check original world. Same deal. WTF Mojang. Either a normal copy deletes mobs, or else a failed copy deletes mobs from the world it is copying and the world that was copied from. This is beyond tolerable. The fact that you spout "Minecraft is a game people can trust" while this stuff is happening is offensive. Get somebody to communicate what you're doing NOW.

It was confirmed yesterday, and have an ADO assigned.

@@unknown , great description! Almost funny, if it weren't really sad in the backgroud.

By the way, interesting your note about the bees not disappearing... bees fly, so maybe this is why they were spared. Did you try to find your missing mobs and entities underground? There are more and more reports of people finding them in caves under the place they were before.

I don’t understand why it is a sister issue when it has the same basic problem. Both should be amalgamated into one as mobs simply should not be despawning and vanishing period. No matter the cause, it must be fixed. All of the causes must be fixed and having everyone on one page to offer up information on the issue would be a better idea than ignoring this bug report while giving attention to the new one that has barely any votes. For all we know it is the same problem. That bug report is basically pointless out the issue or one of the issues which should really have been added as a comment here and not a new report.

migrated 2021-10-20T18:11:49Z

Your comment ignores the fact that Mojang, in the ONLY almost-communication they have done about this has assigned THREE ADOs to this issue. Meaning they consider it three different issues. So no, we don't all know it's the same problem.

migrated 2021-10-21T11:25:48Z

I encountered twice, both times happened around my base, the 1st time I was working inside my base gathering stone at my stone generator. While I am mining the stones, I did feel a sudden lag but I ignored it then kept working for around 10minutes. When it happened, I did c some glitches in the graphic, some tiles disappeared n I can c outside my base for a while, all 4 piston stopped too.

The 2nd time it happened, just now in version 1.17.40, I was AFK in my creeper farm for almost 10hours, so I'm not sure when the mobs disappeared. The creeper farm is located above y level 193 it think, using a trident killer, n the creeper amount is ok, not insanely huge I guess, I got maybe 2 double chest full of gun powder after around 10hours.... Sorry I'm not sure if these details will help with the debugging or not. I'm playing on Nintendo switch.

The 1st time it happened with a smaller radius around my base, the 2nd time is bigger radius. I don't think bees inside the beehive r affected.

I remember something important. I think only the area I recently been through gets despawn. The 1st time n 2nd time I encountered this problem, I was moving between 2 different directions, n the mobs that despawn r the mobs in-between these 2 areas. The mobs in the area that I didn't go for a while r fine.

@nefaeria, with all due respect some of us have been experiencing this symptom of entities disappearing for over four years. It is unfortunate that it seems to have gotten much worse with the latest update, but it is not some new thing even though there may be a new (additional?) cause. There is no practical difference between "disappearing" and "despawning". From the player's perspective, an entity that was in the world and which should remain in the world (due to interactions, naming, and so on) is nevertheless removed from the world. Whether it's due to chunks, distance, Nether portals, saves/crashes, or whatever other cause, the effect is the same (and IMO should be tracked here under this bug report).

The reports of entities being found underground are interesting, but until Mojang provides us some feedback (ha) about whether that is a specific issue unrelated to other entity disappearances, it's all just "where my mobs at, yo?" This is the bug for that.

I would add that it's to the benefit of people experiencing this issue for the first time to join all reports into this ticket, and VOTE for it. Multiple low-vote tickets are less likely to get attention than - and I'm just throwing out an unreasonably hyperbolic example here - a 600+ comment, 1000+ vote, 4-year old bug. As if that would ever happen, ha.

Playing in realms, I lost 3 tamed wolves in about 20 mins. 1 alone, then the other 2. Near base, just working. 2 were killed, but the other 3 just disappeared.

Playing solo, my DONKEY disappeared along with the CHEST and LEASH. I was away from the village but had interacted recently and frequently, and it was leashed to a post.

This is really frustrating, as I know all the PLAYERS understand! What will it take to get a fix??

I have been having random despawns (named or leashed) here and there over the couple of years I’ve been playing as well. But what I experienced this time was not the same. Extreme lag to the point of not moving, 18 armor stands, 18 villagers, 2 dogs, 4 cats, 8 horses, 2 axolotls and a mooshroom cow just gone. The autosave icon came on at the same time. It’s like all the entities didn’t get saved. This was immediately after updating to 1.17.30.

I have since updated to 1.17.40 and have been playing a copy of my saved backup from before the whole loss. Interestingly, after multiple checks, saves, open and closes, everything is staying and I have had no losses at all. There is still a bit of lag in 1 area of my mansion that stops lagging if I look down or walk backwards towards, but no losses so far.

It may be the same outcome, but the bug was definitely different (cause) to the description of this bug report. Hopefully this bug gets fixed anyhow.

It's been frustrating to play recently in my survival world because everything despawns while doing normal day to day things around the base, my base is right at spawn.

If I put any mob, whether it be a cow, horse, chicken or whatever inside the pen I built and go harvest my crops or or just walk around the base for a bit i can expect them to be gone in just a few minutes. Nothing out of the ordinary has been done in that world and its been consistently happening since updating to 1.17.30 or so I believe.

Hardware / Platform: Nintendo Switch
OS Version: 13.0.0
Minecraft Version: 1.17.40

What you were doing leading up to the mobs disappearing
- Traveled to a nearby flower forest to obtain bees, and then upon return to home village proceeded to breed the bees and harvest honeycomb and honey

Single vs. multiplayer, local vs server/realm
- Single player, local

How far you traveled
- From my home village at ~[-1200, y, -120] TO ~[-2750, y, -1600]
How long the current or previous play session lasted
- ~4 hours
Whether the despawns were near a player spawn point or if you had changed your player spawn point during the session
- I had slept in bed at night / reset spawn point a couple of times at regular “safe houses” along the way to / from the flower forest
- Upon returning to my home base-village, I erected 4 bee hives, planced the one I’d transported, and then proceeded to breed the bees over the course of several Minecraft days
- All of my bees disappeared at about the same time all my villagers disappeared
If you experienced lag or anything else abnormal
- The game froze a couple of times but eventually normal gameplay resumed, and I continued
- There were a few instances of lag
- Upon exiting a boat, the boat immediately disappears, and this happens about 99% of the time; if I walk away from where the boat disappeared and return, I find it right where I exited it
- Currently my village has only one vfillager, and that single villager I found outside the village in a minecart.

Platform - Xbox One

Version - Latest release version (I believe that is 1.17.40)

This happened on a mostly single player world, and for the past few months, it has only been single player. I was only a few hundred blocks away, if that. I had been working on a big project near my base for a while, and after a few days of doing that I realized that a number of entities had despawned. Nothing out of the ordinary had happened up until that point. On a previous backup from a few days ago, all of the mobs and entities are still there, so this happened very recently. I am not sure if it is a radius thing, because while all of the villagers in an iron farm despawned, some bees that were closer to me had not despawned. And this is not an entity cramming issue or anything having to do with too many mobs in a small space because 3 axolotls and a turtle in a lake near me that were free to swim around the whole thing also despawned. Also, I do not think this is a chunk borders issue because I made sure that my iron farm was completely within a chunk border, with no border intersecting with the build. Hopefully some of that helps, id love to see this get resolved soon so I can repair my iron farm.

@Kyle
Hi, let me start by saying that I am sorry for your loss. For what it’s worth, my experience with this issue is that the chunk border problem is not only related to keeping your villager locked into a single chunk, but additionally, ensuring that all naturally spawning entities are restricted from entering or exiting the chunk. This includes cats, fish, etc. Also, fencing needs to be set up to keep mobs wholly within their chunk. Typically, if I am really concerned about despawning then I will use solid blocks instead.

For an iron farm, I build underground with a surface level whirlpool to pull in any other spawns and kill them. I then use a red stone filter to filter out any stuff that I don’t want. For trading villages, I use fencing and landscaping to ensure that mobs can’t move between chunks that include villagers. For villages built for looks (Western town, Alien ship, etc) I build them with a nearby zombie spawner so that I can restock the village.

That said, as others have mentioned, this is a very old bug. My kids and I don’t play survival anymore because of it. My daughter still plays the game but only in creative and adventure modes. My son and his friends play on Java. I canceled their realm subscriptions. My point being that the last iron farm I made was a year ago and I haven’t played since, but this might work to fix your farm. I would suggest testing in creative before spending all that time trying to get it working in survival. Good luck!

I spent all morning capturing 2 zombie villagers, curing them, and moving them up to a holding cell at y=210 so I could build a villager breeder.

This is all about 50 blocks X, 20 blocks Z, and obviously about 150 blocks Y away from my spawn.

As I was building, a skeleton knocked me off my platform and it took me a few tries to get back up without being knocked off again. Somehow in that process, the 2 villagers despawned along with the 3 minecarts, cat, 2 chickens, and 8 sheep that have despawned every other godforsaken time this happens.

It's getting hard to think about bothering with the game. I have to constantly make copies of the world and for every 2-3 hours I play I lose an hour of progress. Why on Earth would I pay for a Realm subscription while this is going on?

migrated 2021-10-23T23:58:17Z

Spent a day AFKing at my mob grinder. Healed at least half a dozen zombie villagers. Flipped back to peaceful mode after curing the last villager so I could get them back without any mobs killing them. Got them all back to the base and assigned workstations.
Came back the next day. Did some fishing. Went to check my pets to see which cats I still needed to tame.
All are gone. Cats. Wolves. Sheep with leads. Every last villager, including the sole survivor from the beginning of the playthru.
None were free roaming. All pets were sitting. All villagers were trapped inside houses.
Very annoying, as I had also just finished building a trading post. Not to mention all of the lost resources from healing the villagers. Even the leads vanished.
Haven't checked other villages, as the only one nearby with people is almost a thousand blocks away... I'm too frustrated and shocked at this to bother checking them, and I don't want them to vanish too.
Mobs still spawn though. It seems that only the mobs I actually care about have vanished...

Details:
Platform: Switch (which in itself is buggy af) Using the gamecard, not a downloaded version. Single-player, Peaceful mode. Version: 1.17.40. (I've had several problems since getting this update, this is just the most irritating...)
What was I doing: Building, fishing. No idea when everything vanished. They could have disappeared right after I logged out yesterday for all I know... I only just checked everything after building the trading post.
Travel distance: I didn't leave the base area. So I was near my bed spawn point. Within 100-200 blocks at all times.
Play time: about 2-3 hours on this session. No noticeable lag (for a change. Thought that was sus...)

migrated 2021-10-25T14:45:37Z

On the Switch, using a physical game cartridge, on a world that started around 1.17.10, and was updated to 1.17.40. Single and Multiplayer (couch co-op split screen, not network). This was not our first session on 1.17.40, and we didn't have any issue with mob depsawning in other sessions.

Yesterday, we opened the world to find all normally stable mobs despawned in our shared base. Tamed wolves (named and unnamed), cat, sheep, cows, pigs, chicken, salmon, unnattached trader llamas, named zombie, villagers, and minecarts. Interestingly, the one bee we have was inside its hive when we loaded the world, and it persisted. One strange thing I noticed was that a cat spawned near where the villagers were located before they despawned.

In the session prior to the despawning, three of us went adventuring. We had all double checked our respawn points were set in our houses in the shared base. We disabled a Haste 2 beacon by removing a block from the 3x3 layer. We flew away with via elytras, and went roughly 1000 blocks from the base for 30 minutes doing some fighting and mining. We then flew back, and I believe all the mobs were still spawned correctly at the time of our return (I'm not 100% certain). We did a Save and Quit. I think one of the players who wasn't the "main" on the world did Save and Quit individually, and then the main player did a save and quit (which automatically exited the other remaining player). It's not uncommon for us to have the main player Save and Quit with other players still active, which closes all the other sessions, and has never been a problem in the past that I've seen.

We've been on similar adventures before, but this is our first one on 1.17.40 where we traveled any notable distance.

migrated 2021-10-25T20:20:27Z

Wow. I just came across this old ticket. I thought my occasional animal losses was my fault. I've been playing an "island survival" game ("Ocean Monument Ahead" see from the seed picker) for nearly two years, since 1.14.

The first disappearance was a Mooshroom that I brought in by boat and lured with food into an enclosure. Then a Llama I had ridden and got from a wandering trader disappeared. Then a pig. And a sheep. And others. Most recent was a horse I had ridden, saddled, armored, and tied to a fence post. It was there for months, and now it's gone.

I thought maybe the "disappeared" had been hit by lightning or something. I wasn't aware that it could be a bug in Minecraft.

I suspect this happens when there is a game update. The number of updates does seem to correspond roughly to the number of animals I remember losing.

Hopefully any of this is useful.

what you were doing leading up to the mobs disappearing: Gathering from my farms and trading with my villagers.
single vs. multiplayer, local vs server/realm : Singleplayer, offline
how far you traveled: max of 40 blocks, everything was contained in my base which is only about 60x60 at the largest points. My trading hall is located in the center of my base. Important part though is that I never got far enough away to leave render distance.
how long the current or previous play session lasted: About 30 minutes
whether the despawns were near a player spawn point or if you had changed your player spawn point during the session,: Literally the chunk over from where my spawn is set, but 200 away from the spawn chunks if that's what this is referring to. Spawnpoint wasn't changed.
if you experienced lag or anything else abnormal.: Several villagers had their trades lock up entirely despite them all being stuck in a 1x1 area behind their respective work station. Even broke and replaced the station to make sure they were still connected to it (They were)

And if it matters, I lost about 40 villagers, all locked in place and unable to travel even a single block, as well as my entire wolf and cat armies (About 10 wolves and 16 cats), both of which were sitting around my base, as well as 2 nametagged skeleton horses I'd built a small barn around. 2 farmer villagers who are set up in small, enclosed farms are still perfectly fine though, and they're located in the same chunks the trading area is, just 14 or so blocks higher up. An entire village also despawned that's about 100 blocks away from my base. Switch Edition.

I see they have added a new bug (MCPE-144208) specifically for mobs disappearing "on logout or when leave area". I guess the "on logout" could be some specific new thing, but "on leave area" is also an event that precedes, in some cases, our own favorite bug here #21416. I love you guys, we're like family now. But anyhow my concern, which with $2 can buy you a cup of coffee, is that that other bug gets investigated and solved and closed and us poor slobs over here continue to languish. Even though our mobs disappear "on leave area" all the time.

And really, "on logout" isn't unheard of here on 21416 either. It's maybe just not the entire mob collection that reliably goes >poof<. I guess if they can fix 14428 at least the game will go back to being as annoying as it was before 17.0. If I were a glass-half-full person, I'd say the 17.0 problems are probably just a misguided attempt to fix the overall despawn issue. They really are trying to fix it! <unconvincing smile>

If you are experiencing all entities in a chunk or larger area despawn on reload, please follow and vote for MCPE-144208, and refrain from telling your story here. We can’t always distinguish that from this older issue, but there is definitely a new problem since 1.17.30 and Mojang has decided to track it separately.

This one looks related to this problem, too: MCPE-141539: Projectiles launched by the player fall through blocks, sometimes into the void, when player moves far away.

It's exclusive about projectiles behaviour, but maybe it's also affecting all entities: when the chunk is unloaded, the entities present in it fall to the void because the terrain blocks aren't present.

im playing on windows 10 realms
the newer mobs seem to disappear at a much faster rate. for example the original 8 horses we had took months slowly disappearing one by one. However recently I bred a large amount of sheep knowing some would disappear, however within 3 days every single one was gone. Have had this experience with the rate of other mobs vanishing as well.

A fenced in iron golem, entire fenced in villages, fish in a tank, etc. All despawned. But only if my player 2 was in that area. Very upsetting, because I had many of them named. Even despawned a fenced in horse with armor and a saddle, on two occassions! All the sheep, all the pigs, etc. I need them to undo the new update, cause it didn't happen before.

Recently I almost lost a village of 30+ villagers. The village is walled and sealed completely. If I am within walls, everything is fine. I save and quit as many times as I can - no problems. Two days ago I went outside the walls, spent about 2 Minecraft days outside, exited the game whilst outside, loaded and found that all but 3 villagers disappeared. I restored the population, expanded it to over 40 villagers and 5 golems. Today I left the walls again, spent outside 1 Minecraft night, had to close the game. When I opened the game again and came back within walls, the entire population of 40+ villagers plus golems were lost! Not to mention the fact that a lot of resources to make them dimond gold etc went to waste. Ah yeah and since the entire village is dead now, I can not regenerate them, and what is the point they will disappear again anyways. This issue is going around for some time now and is still not fixed. It takes a lot out of the gaming process.

On the same topic, mobs that have been tamed and name tagged have all despawned when i load into my long-term running (1.14 start) world. My trading hall of 40+ villagers and all the tamed dogs/cats in my house too. This has happened twice, and i luckily made copies beforehand so i could keep them. I have lost a lot of progress, and they all stayed in their same spots. The villagers in my trading hall have 1x1 stalls i keep them in. The tamed cats and dogs on the other hand, werre all siting on my house, not being touched. Armour stands in my house also despawned, and iron golems on leads i spawned myslef dissapeared too. This was all within the chunks of my base when i logged in at my base.

I have also experienced this bug, playing on the Xbox One S, single player, local world (not realm/server). Around the time of disappearance, I was doing some heavy traveling, through the nether, to about 3,300 x and 650 z further from the animals (4200, 10, 2265 were rough coords I travelled to). One animal was within the player spawn chunk and the other was about 4-6 chunks from the spawn point, I don't believe I changed spawn points during this time. No serious lag issues in my world, some frame rate dips near my base, I suspect due to the amount of chests and animals close by, but this is typical, not unusual.

I had a previous save with one of the animals, went back to that, tied him to a post, and he has stayed spawned in my world through the past week or two, even with an instance of the same travel distance.

,Update on this bug.
This bug is still happening.
Both villagers and animals are vanishing randomly.

It happens after I have been playing for hours, with mastered trade level villagers that are named, then closing the game for rest at night and reopening the game the next day for play. I find several villagers and befriended animals gone, again, on a daily basis.

Out of 15 villagers, i am losing 6 to 8 at a time, the next time i open the game to play. These are named villagers that have been maxed to the master trade levels. Several were rescued zombie villagers I saved.

I am building around the village, not venturing far from them, usually gathering supplies from my farms, and building or mining in the area.

They only vanish after i have closed the game. I have my avatar sleep in a bed near the village several times during play.

This is happening on a daily basis for about 2 weeks in my friends survival realm. Another player in this realm is experiencing the same problem.

I am playing the Bedrock edition on my PC.

McclellandKmra 2021-11-12T00:33:15Z

This happened again on my long term survival world (xbox one, bedrock, latest version), I was away a couple thousand blocks working on a farm, as well as a few hundred blocks away working on a build, and some more mobs confined in a small area disappeared, including name tagged villagers, chickens in a pen, and tamed cats and dogs. This hadn't started until recently, and since then its been happening a lot.

migrated 2021-11-12T05:33:57Z

I have villagers in my artificial village (used as an iron golem farm) strangely despawned at least 3 times. At first I thought that there was some loopholes when spawn-proofing the village, that a zombie spawned, killed some villagers and is eventually killed by the iron golem. But later I concluded that it must be a bug because, for twice, I failed to repopulate the village completely (they won't breed any more), and at the end found an old villagers locked in an "impossible place": besides a trap, at a 1-wide 2-tall 7-long trench that has no entrance (because all around it is a wall leaving only a 1-tall space for me to see and kill the mobs inside the trap). Each time 3 or 4 villagers (of the 20 in that village) disappeared, and 1 of them is found in the trench. This does not happen often, my estimation is once a month when I play the world one or two hours every day and visited the village once or twice a day.

It happened on 1.17 (forgot the patch level, but not the most recent one), in a world originally created on 1.16. It is a single player world, only myself can access it. And I routinely exit the game with "Save and exit", not by closing the application window, although I might have accidentally hit the close button a few times.

I know the bit of info is hard to use (I write code too), but hopefully it gives the developers some ideas about what might be wrong (i.e., the mobs might not have simply gone, it could have been incorrectly positioned).

Another perhaps related observation is that there are usually unexpectedly large number of mobs around myself. That is, when I say "/kill @e", there are too many cats, dogs, sheeps, etc. I discover that because my hostile mob farm and my slime farm stop producing anything, although I counted all the mobs around myself and thought there there should still be ample of counts before the global mob count bound is hit (it isn't even half full). I don't know why, but in the most recent version this seems to be eased. Perhaps it is something to do with the render distance? Again, just mention that in case it is useful.

Isaac To: Could we get a copy of your world save, or screenshots of the area where villagers should be a where you found them, or at least coordinates? Your account is highly interesting to me because we have had a few other comments over the years suggesting that mobs might be getting displaced and then killed rather than just deleted.

This has been happening to me recently on an Iron farm off the main area in the end. 20 villagers were carefully nametagged and placed in a 7x7 confined area. No problems at first, then it was brought down by half suddenly (10 villagers). Then I replaced those missing villagers with ones nametagged separately 1 through 10. The next time I checked, a random 4 of those sequentially named villagers were missing, with 2 left over from the initial 20.

Replay from @unknown: after looking at the video, I think the villagers could be walking over to the trap just like you did. If you're interested in testing, you could make a creative copy of the world and setup a tracer: a repeat command block executing on every tick with /execute @e[type = villager] ~~~ setblock ~ ~100 ~ glass. Then let the world run a long time.

migrated 2021-11-20T13:39:17Z

GoldenHelmet: You missed the point.

(1) Even if what happened is what you said, it isn't reasonable: the villager has no ability to jump over the fence using the carpet as I did myself. The whole point of the design of the trap is to ensure that no villager can get anywhere dangerous. Of course, if the villager gets "teleported" to outside the village, that is another story.

(2) But that is not what actually observed. The villager is not at the place I finally stand, but in front of it. That is, it is in the trench between myself and the magma block (right above the chest if you can see it). At the end, to rescue him I have to break blocks so that I can enter the trench and push him out.

There should be absolutely no way that the villager could get to that trench. There is a row of upper slabs above the space he stand, so the trench actually has a height of 2.5. But to enter there he can only reach from the platform where I finally stand, which is 1 block higher than the trench. The space for vertical entry is only 1.5-tall. An adult villager has a height of 1.95, meaning that he cannot enter, just like I cannot enter. Can he be a villager who entered when he was a baby? No, he had trade experience. So the only thing I could imagine is a bug.

Edit: (1) I can reproduce villager lost in that world, by closing the windows without using "Save and Exit". Which is pretty much what the earlier comment of this bug says: across chunk border, mobs can get lost if you don't close the game properly. (2) Even if that happen, I cannot reproduce the problem that the villager get stuck in that trench.

I can imagine that this is actually a separate issue, perhaps it happened some time ago and I did not go down to the trench to see it when it is triggered, and when the villagers are actually lost I wait for it to breed but it stops when one bed is still "unowned". If I remove that bed and place it again I see green particles. At that point I know some villager is at a strange place, so I look for him and found the previously stuck villager. Just one possible explanation.

Recently I started playing on an experimental world with the new terrain generation. We created an animal enclosure with 7 sheep, a chicken, and a cow. Besides that, we also locked up a villager (which we abducted from a village) who sold us mending. The villager was locked up with a number of fence gates and iron doors to get out. The area was brightly lit so no mobs could spawn.

After a few in-game days, I noticed only 5 sheep and the cow remained in the animal enclosure. After another 2/3 in-game days, only 2 sheep remained, and the villager was also gone. While I know chunk borders are often at fault in cases like this I checked if the might be an accidental chunk border in the enclosure or villager cell. But both of those were in the center of a chunk.

The fact that this happened so regularly (every 1 or 2 in-game days another one would disappear) made keeping animals/villagers impossible. Both the animal enclosure and the villager cell were within 50 blocks from my base and I did not travel to the nether or further than 100 blocks away from my base during the days the disappearances happened.

A few hours game play.

Died in the nether.

Spawned (not automatically) at my usual spawn point (which is different to my original in this world.) Spawn point is close to where the animals were, and the portal.

All bred animals gone.

2 armour stands and armour gone.

For a couple of months the nether has been very laggy for me. Today (just before animals and armour stands) disappeared it was extremely laggy.

Overworld laggy for a few days too.

For a few weeks, in the overworld, my boats have also been despawning when getting out of them a fair distance from my spawn point.

Today I took a dog to the nether, to see what would happen. After a while I thought he'd died (fired at by ghast) but it was so laggy I couldn't tell and didn't get a notice that he'd died. That must have been the moment everything disappeared!?

A few days ago a dog and a cat disappeared (by my spawn point) the next day I found them sat in a boat together (near where I'd lost them.) ..... the boat probably popped up after it's own despawn!

A few days ago the wandering trader and a chicken joined me in the nether.

I was playing single player in my own vanilla created world. No add ons.

I play most days for a few hours at a time. Sometimes it seems to get more laggy the longer I play?

I was thinking the Xbox live was the issue for my villagers and entities to have randomly disappeared and so I thought once it recognized that I'm signed in, it would fix itself. Nope not the case. Villagers and entities(in my case farm animals) still completely gone. I even ran over to my 2nd Xbox (one edition) and went to settings in Xbox to turn off network sharing of files and opened up my save from 11-21-21 when I knew the animals were still present and even with the network share feature off, the villagers and entities were still all gone.

Before I saved my game yesterday, I was in the middle of trying to create an iron farm and was trying to transport some already contained villagers from my first failed iron farm over to my new one via minecart and rail. I eventually gave up because it was a difficult farm to make while in survival mode, so I went to my Iron door bunker below my first failed AFK iron farm to save and quit so I would be safe from mobs in case I ever forgot I signed back in and walked away (which didn't happen). While in the present bugged game, I ran over to the closest village to see if any villagers were present, and yes villagers in the next village over were present.

Seed: 121281975

Save coordinates when bug was noticed - 2816 - 69 - 1751.

I do have a copy I made of this world in creative mode in which I did not create the iron farm or village breeder if someone wanted me to test if the bug would trigger again.

Please and thank you,

Hope the bug is resolved soon.

Most of you people commenting who have been getting this bug recently are actually getting MCPE-144208 I think there has been a bit of confusion with the two from when people reporting the new MCPE-144208 bug would just get told that MCPE-21416 includes all disappearing entities however now it was given its own bug report.

migrated 2021-11-28T07:22:37Z

I found this report and believe it is connected perhaps. If a mod could check it out maybe it could help. MCPE-147265

It is related to the teleportation of villagers.

Reply from @unknown: thanks for mentioning that report. I'll see if I can get enough info to reproduce it.

migrated 2021-11-29T04:00:13Z

I have a theory that it is involved with the chunks, I have a massive sheep farm with large sections dedicated to each color, after the bug, two sections were unaffected, some had about half missing, and the remaining had no sheep at all. On top of that, my villager trading hall was unaffected, yet the villager breeder I use to supply it was completely wiped when it isn't that far away.

CoolAbhi1290 2021-12-04T23:03:22Z

My brief testing indicates this happens when you load into a world. Saving and quitting simply "primes" up the bug.

Reply from @unknown: if you are not going to elaborate on your test methods and results, then this is not helpful comment.

I'm playing on an experimental world that was made in 1.17 and then played again 1.18. I don't recall anything dissappearing before I loaded the world in the new version. As of now, my fully enclosed villagers (who are very much stuck and safe in their enclosure) have been dissappearing seemingly at random when I AFK at my skeleton farm for extended periods of time. The farm is far away enough that the chunks aren't loaded (I believe), and when I afk, my screen stays open on the world.

I was unable to re-breed my villagers without adding new beds, even if I broke the ones attached to missing villagers.

migrated 2021-12-07T12:00:16Z

Reporting for only villagers. 3 villagers despawned realms 1.18. along with a named zombie villager (uncured)

Zombie villager: (in boat, under shade, time=night) i log out.10 seconds, friend logs on. checks and zombie villager gone. boat exists. both entities were not near any chunk borders (checked with chunkbounds, mcpedl) and no alt+f4 as android phone.

villagers: one lost when afking ish 100 blocks away. difficulty changed from peaceful to easy and back. two lost when entering nether to xray for debris. difficulty was changed from easy to peaceful.

also, idk if this is a new bug, but entities can go invisible when player leaves boat. leaves a dark circle below where it last stood. (which states i exist) Then idk lag or smt, the image shows but only for split seconds, Not in the original spot. Fixed by save&quit, then rejoining.

Updated to 1.18.1, villagers named. no problems so far. they are almost constantly rendered and monitored trough spyglass (when i needed paper to lock in mending trade)

additional info: playtime was about 4 ish hours with breaks every hour or so. villagers were from a now dead 1.17 village. one from 1.18 village that despawned. current ones are from the same 1.18 village.

All entities are still vanishing in 1.18 and now 1.18.2 on nintendo switch when traveling distances or going into the nether. Name tagged ones as well. Even if they are locked into a 1x1 block and unable to move or cross chunk borders. Simulation distance of 4, 6 or 8 chunks does not matter or affect the disappearance in any way. Save and quit also has the same affect on mobs and entities.

migrated 2021-12-14T04:43:10Z

Yeah I agree I am having all my villagers disappear in windows 10. It happens when I save and quit and rejoin or when it crashes. It has also been crashing excessively while saving. This is a new problem that came with 1.18.

Can I please send you my world for you to look at. My horses, villagers, pandas, minecarts, and pets are all disappearing and there's no real rhyme or reason. I have the world file on my desktop ready to send where do I submit?

Reply from @unknown: what you are experiencing is tracked at MCPE-144208 and we would love to have a copy of your world save.

My husband and I play together on the same Xbox (he has a live account and I join in) and three times now we've had mobs disappear on two different seeds. The first time neither of us were near the mobs during load in. The second time we had a new seed and again neither of us were near the mobs. The third time I was in the same area as the mobs during saving, however my husband was not, maybe a chunk or two over. When he loaded the save back up our mobs were gone.

The first two times there didn't seem to be a whole lot of lag, however this last time the game was very slow whenever we were around our mobs, even before they disappeared.

Also, I don't know if it's related, but we also experience the glitch that makes players load in without the correct inventory (empty or incorrect items entirely), and wrong spawn point. However it only happens on mine. Unfortunately I did not join the game after realizing our mobs were gone so I do not know if my inventory was also bugged. It still makes me wonder if it's an issue with save states and less with chunks specifically.

The Axolotls in my world keep despawning after reloading 2 of my worlds. Both of my worlds are multi- player. I've put them in bucket before putting in the water. In one world I live in about 50 blocks away from the lake. My spawn point is about 2000 blocks away from world spawn. In my other world I was only about 10 blocks away from where I placed them. And they despawned.

On PS5, Realms, right before the 1.18, we had never experienced any issues with disappearing villagers or animals. We had the usual farms and villager trading halls-no issues. Been playing on console since the takeover from 4J, no issues. We started a new realm after 1.18 dropped and suddenly, we can't go beyond one map or something disappears. Really randomly. 2 sheep once from my 18 sheep. One of two pandas, in a fence. A villager here and a villager there. It's very disconcerting and I read here that this bug has been happening for years so it makes me concerned that it's elusive and, now that it's happened to me, will be pervasive.

I though it might be a spawn issue but my partner is on another map and just recently went into another dimension ~~over several maps~~ and when he returned, 2 of his 3 villagers were gone.

I would be happy to give you access to our current, bugged, 1.18 or previous 1.17 realm where it did not happen.

The related bug was fixed in yesterday's beta (1.18.10.26 Beta) was a separate issue (MCPE-144208) to the one being tracked here. We are still working on this specific issue, and hope to have it resolved as soon as possible.

For some reason every colour sheep except yellow despawning, also cows. Everything else despawned in a pretty much every where, even my dogs😞

TheTamedWolf 2022-01-18T21:39:24Z

For those that lost their animals while having them tied to a fence, i urge you to look at the last place your mob was tied up at before that. I just found my horse at the last place it was tied to a post before this last fence. It was out of render on my Realm; it had been a couple play sessions a few hours long. I think maybe it's a type of 'lag' memory thing. It may even impact all the other situation regardless of leads or fences. I hope this helps any!

Happened to me for the second time on my Xbox one s world. Last time it wiped out all of my mobs which couldn't move very far already. This time it wiped out most of them and I noticed it cleared all of the snow blocks in the area from falling snow. I noticed everything gone upon logging in both times long play times both times that mightve contributed to the issues, but not a lot of traveling around when it happened either time that I can remember.

@unknown the issue that was fixed in 1.18.10 was MCPE-144208. This issue (MCPE-21416) has not been fixed yet (tested on 1.18.10, 1.18.20.25, and 1.18.20.26).

Added several mobs back to my barn following the update fixing the mobs despawned issue. After that, like many have noted, I traveled through the nether and back to the overworld some decent distance away (a couple thousand overworld blocks). Mobs in the barn were gone when I returned. All mobs had been bred before being left alone, and corralled in an 8x8 space (different spaces for each animal, so they couldn't all be on a chunk border).

Trying to remember for sure, but possible that I died at some point nearby the barn during the same timeframe. Not 100% sure on that, though.

This was on Nintendo switch, local single player, in a world that has been around for several years now.

asaellam 2022-02-13T04:43:27Z

This just happened to me on 1.18.10. Initially, I had ridden my horse from my house to my End Portal (about 1000 blocks away). After returning from The End, my horse was gone, but the lead was still on the fence. I returned to my house to find my horse back in the stable. This horse is named.

After sleeping, that horse and another named donkey were gone. All of the other unnamed animals were fine.

compuparker86 2022-02-22T17:43:24Z

I just had a similar horse issue. Three horses, two with saddles and armor, one without armor or saddle. All three attached with leads to fence posts in three different adjacent chunks. All three are now gone with leads still attached to the fence posts. I’m on switch with 1.18.12 May or may not be related, but game is also crashing intermittently when saving, maybe 3/8 saves. Does not appear to have crashed until after the horses disappeared (crash only happened after noticing the horses missing).

Named villager despawning is one of the most disheartening events a family playing together can experience in MC. Collared dogs seem to be handled more appropriately, and they can't even be leveled. A console message when a named villager dies (or a pop-up tombstone) would at least let us know its your Thanos Bug that's killing our townspeople.

Returning from a town by rail to find only 2 of the 8 named villagers remain is the bug most likely to result in cancellation of realm subscription.

migrated 2022-03-31T03:18:30Z

this is easily the most frustrating part of playing right now. I can watch mobs popping in and out of existence in front of my eyes. Horses disappear when I turn around to grab a saddle or a lead. ridiculous how glitchy this is

owlfalls35 2022-04-11T11:34:13Z

I think this might be caused by autosaving. I noticed that they despawned when the game crashed during an autosave. The developers could temporarily disable autosaving in the beta to see if this issue persists even without autosave.

migrated 2022-04-12T17:45:42Z

Started occurring in new realm, less than a week ago. Since then dozens of mobs have permanently despawned. It seems to occur each time I log back on to the realm and find more mobs are gone. Extremely problematic for game play...

migrated 2022-04-12T18:33:41Z

This has been happening on our realm lately, specifically -

Horses or other entities, tamed, tied up with a lead, will disappear if I leave the area and come back. The horse, and the lead, will be gone.

Anything left in a boat, that was previously tamed or interacted with, will disappear if I leave the area and come back.

Leaving the area means leaving the render distance. This happens when I'm only moving in the overworld, and haven't logged out or exited the game at all.

We play on peaceful, so nothing nefarious is happening from hostile creatures. It happens when I'm alone on the realm so it's not from another player.

This is in addition to the mobs that disappear when I log back in to the game (which I feel is the chunk crossing issue possibly, but that is still very much happening).

migrated 2022-04-30T07:50:23Z

Hopper in minecarts despawn from realm when anyone logs in. Animals with nametags also despawn. So annoying. Been happening forever...

GoldenHelmet 2022-05-21T12:11:55Z

We would like to know if anyone has noticed any mobs missing which were created or loaded correctly at least once after the 1.18.30 update.

Changes were made to how entities are stored in the world save in 1.18.30 that we hope would improve this issue. It would only affect how mobs are saved after the update, so mobs that you last saw before the update may have failed to save before the update released. The update released April 19. Some Realms and servers may not have updated until a few days later.

migrated 2022-05-25T20:48:00Z

I have still noticed lots of issues with villagers despawning, mostly ones that aren’t trapped in a 1x1 space. I’ve had villagers that are free roaming a certain area in my trading hall disappear while I’m in the trading hall, sometimes when I save/reload & sometimes w no apparent trigger. I’ve also had the farmer villagers in my auto carrot/potato farms disappear after replacing them a couple of times (since 1.18.30), the fletchers who are trapped persist but not the farmers 😢

EDIT: I’m playing a single player survival world on Switch, about 450mb

Reply from @unknown: could you provide a picture/screenshot and coordinates of the part of your trading hall and crop farms where villagers repeatedly disappear? Are you absolutely sure they are not getting out, falling, or otherwise taking damage? If you are playing on easy difficulty, zombies could spawn, kill them, and then despawn without leaving a trace.

migrated 2022-05-29T15:53:54Z

This is still happening on my server. It was originally 1.16, has been upgraded to 1.18.30.

I'm playing on Realms.

The mobs that disappear are at spawn.

We're traveling to very distant areas and returning to spawn to offload our things (via teleport).

Cats, dogs, and parrots in the house don't seem to despawn, but wild animals do, even with a name tag.

Sometimes the chunk with our house is active when no one is there, sometimes it is not. Our house is within 200 blocks of the spawn point. It seems not to be active if we haven't been there that day, but not if we haven't. I know this because sometimes animals from home get tpd if I tp all animals of that type, but sometimes they don't. I had to change the names on two of them, who were copied somehow, because of this problem. We had two with us and sent the copies home. It was fine to tp the ones with the same names until we went home, then we couldn't do it anymore.

We spend varying amounts of time away from spawn. We will typically play for an hour and a half to two hours during the week and might go there two or three times each for up to 10 minutes. On the weekends we might play for several hours.

We rarely sleep there and usually only stop by to drop off our things. When we have spent nearly all of our time at spawn the mobs don't appear to despawn.

We do sometimes replace our world with a back up.

GoldenHelmet 2022-06-01T14:50:35Z

In Sheri's world the mobs are able to be tp'd probably because they only get removed from memory if everyone changes dimensions or leaves the world. As long as you have loaded them once and at least one player has continually been in present in the same dimension they never get removed from memory. That behavior is tracked as a bug in its own right at MCPE-77266.

NeoCyania 2022-06-08T13:57:51Z

This is still happening in 1.19. I just had 2 frogs in an enclosed area despawn. One time when I left the area by flying and one time when i used a portal. The enclosed room has a chunk border in it. It happened in the nether where I wanted to make a frog light farm. Very annoying when the frogs transported from far away disappear for no reason (they were fed and interacted with). I don't even wanna risk getting allays because they are likely all going to despawn due to this bug over time.

Just lost 10 hopper minecarts in a single-player 1.18.31 world on iOS. They were immobile and not near any chunk border (they were in a chunk-aligned structure, so I was careful of that). This was a creative world with cheats enabled where I was designing a farm to later build in survival; the hopper minecarts disappeared at some point while I was 1) copying the world to make backups 2) using a /fill…destroy command on a copy of the building (made with a structure block, whose saved structure from before 1 included the hopper minecarts) 3) saving and quitting, and 4) rejoining and quitting two or three times before noticing the minecarts were gone. While I cannot be completely certain, I’m pretty sure that I never left the simulation distance of the hopper minecarts; so, great, it seems like this bug can rear its fangs even when using the game’s own save-and-quit button, though obviously this instance could involve me running a laggy /fill command. I suppose my takeaway is that I simply have to accept that I’ll inevitably spontaneously lose a dozen blocks of iron each time this happens after I build it in survival. Booo. (Oh, I didn’t report other instances when they happened, but I have of course had minecarts disappear previously, but those were on chunk borders so honestly it was bound to happen.)

I just went over 2000 blocks to get Allays and then brought them back to my house and put them in a cage so they wouldn't float around, went out mining for a bit, came back and 3 Allays in the cage had disappeared, they were name tagged and everything, this bug is so bad now especially when you have something hard to bring back like a frog or an allay just for it to vanish for no reason whatsoever, checked and the wall of the cage was a chunk border. Please can this bug be high priority, it's killing the want to play the new update a lot sadly. Thanks for the hard work

Very frustrating. Just happened to me in 1.19.10. Axolotls despawned from a pond I had built for them. Bedrock version, was hosting a LAN session from this PC with a Switch. Logged in, loaded and unloaded the area several times using a nether portal, then noticed the pond was entirely empty. Axolotls were not nametagged, but had all been moved via bucket.

I think someone should make an addon of some sort that can list entities so that we can track them up to the point they randomly despawn. If that won't happen, then another thing we could try is to have a spectator keep an eye on mobs.

If the player has more than 4 frogs in a confined space (not sure if it’s a chunk) they will randomly despawn until there is only 4 remaining in the area. This is not related to mobs despawning on game loading (I always save in the nether to avoid my mobs despawning).

This bug is recent; not sure if it was introduced in the last update, or the one before last. I’m using bedrock on an IOS device.

also note that the other persistent mobs in the area are not despawning; only the frogs.

In 1.16 (pre-C&C pt1), if there was a blackout I lost a couple of plains villagers and penned in coloured sheep/armored horses.

In 1.19.81 only frogs despawn 1 by 1. Enclosure, nametagging, leashing or breeding not enough to save them. Nearby horse pen has no issues.

Survival. Base about 100 blocks away from plains village, with world spawn about 150-200 blocks from village. Swamp probably 1500 blocks in other direction. Frog enclosure near tons of chests & item frames, if that matters.

Still an issue in Bedrock v1.19.83 Realms. All of my 11 lost villagers were within chunks and unable to cross other chunks, name tagged, fully maxed in trade level, and all cured 3 times. The Nether portal is approximately 100 blocks away from the villagers and I traveled 4000 blocks in the overworld through the Nether before coming back and seeing 11 out of my 13 villagers gone. Before, they existed but once I went working inside the Nether and came back they disappeared, it was around 20 minutes I believe and I logged out once being inside the Nether.

what you were doing leading up to the mobs disappearing: Moving items from my old house to a new tree house;
single vs. multiplayer, local vs server/realm: Bedrock 1.20.1 Realms server;
how far you traveled: ~ 150 blocks distance;
how long the current or previous play session lasted: Probably more than an hour;
whether the despawns were near a player spawn point or if you had changed your player spawn point during the session: I had a new spawn on the tree and have probably slept on both places during moving, so yes to spawn change;
if you experienced lag or anything else abnormal: nothing abnormal.

This issue has happened 3 times in total now, each time they have been safe from mobs and have not been on a chunk border (this has only happened to me in previous worlds when on a border so I made sure no one was this time!)

Idk if this would count as new or valuable information, but this glitch seems to apply to boats and chest boats as well. I parked a boat at my dock in one of my worlds and, without warning, it disappeared. Now my other boat, in the same world, has disappeared, though it's just a copy of the world. I've used "/tp @e[type=boat] @s" and "/tp @e[type=chest_boat] @s" to check around the map for either boat. I even used the specific name to get my boat, which worked for one of them until it despawned. This is all in 1.20.15 btw.

Basically, if you have anything valuable, don't store it in a chest boat because it might disappear, even after being named. Hopefully this information is helpful. I hope a fix comes soon, because not knowing if a named mob, leaded horse, or even a chest boat will remain is incredibly frustrating.

All the mobs I've lost are the ones that were on a lead.

Can confirm issue occurred in my world in BDS on version 1.20.41. Old flock of sheep disappeared after building a barn extension which allowed outdoor pens of 18 × 18. Thinking the pens were too large allowing for despawn, bred 2nd flock of 16 and named-tagged them. This flock too has now disappeared. The two llamas and camel remain.

Hi, I have same problem on realm. I play on v1.20.41

I was playing on local world all this time and I did not had problems. Yesterday I have made realm for 2 player (3 including me). Was showeling dirt to level ground and was observing animals around poping up or disappearing.

Locked one sheep in pen. I went to cut some wood nearby, returned, no sheep in pen.

Now I got on my house roof. Looked around and found pig in my pen, in different direction black horse. On different side sheep. No more animals. Walking on house roof 10x10 and looking around found two cows near horse, after tunring few times around cows wanished. After some time block horse become two brown hourses. Continuing to look around at some time two horses become one chicken.

Now in my pen here are one pig and two sheeps.

Animals disappear and appear so rundomly and fast, that I don't think this realm is playable.

this is still happening in bedrock 1.21.1

migrated 2024-07-09T14:36:46Z

This still happens in 1.21.1, and i experience this mostly with pillager captains. I know after a certain time they are supposed to disappear, but instead what happens is, you see a pillager captain. You turn around and the captain has already de-spawned ( It takes about 2-5 seconds for the pillager to de-spawn)

Platform is Switch.
Utilizes realms, single and often multiplayer.

Each play session lasts 1-2 hours.

There are occasional forced logouts due to network disconnections, and sometimes you have to log out to run errands during multiplayer games.

Neighboring villages
It is about 300 blocks away from my house.
When I go there occasionally to run errands, several villagers who should have a transaction history are gone.
A few cats that were always with me are also gone.
Fences and lights are already in place to protect the village.

Distant villages
A village 1,000 to 4,000 blocks away from your home, a village you saw or stopped by while mapping.
A few days later, when I stopped in the same direction for work, it was uninhabited.
Not only were the villagers gone, but so were the iron golem, the cat, and the livestock inside the fence.
On my first visit, I went to bed at night and left there during the day when the weather was clear and there was no hostile mob.

Experienced this issue on 1.21 (best guess 1.21.1.x - 1.21.3.x). World initially LAN co-op 2 players PS4 version on PS5, uploaded to Realms about a month ago. All entities now disappeared were initially contained / interacted with before upload (unsure if this is relevant).

Villager trading setup with 4 of each profession created while world was lan co-op about 1.5 years ago, all villagers locked in with at least one trade, most fully upgraded.

After searching through backups over the course of a few weeks, returning to the village in downloaded backups shows villagers progressively disappear over time while unloaded (players 2000+ blocks away, never visiting trading setup between backups). First backup 3 missing, next backup 1 week later a few more missing, next backup 3 days later a few more missing. Today nearly half of the villagers are missing.

There is also a grid of all sheep colors established 1-2 years ago at a base that would have been loaded a few times between those backups where some sheep have now despawned while contained in 4x4 walls.

They got lost because I trimmed a chunk using Chunker to reduce lag, now they're all gone

On my realm I noticed all hostile mobs despawn at 2.5 chunks away (measured using foxys markers). Had also been having trouble with non hostile mobs unpredictably despawning but I just saw why it happened; I went into spectator near some non hostile mobs that I could see from my vantage point, as soon as I was in spectator they despawned. I tested this again and they didn't despawn so it is intermittent, maybe because it was the first time I went into spectator that day so only that first time caused it or maybe only happens sometimes. Also not sure if it is related but both type of squid only spawn in newly loaded chunks not anywhere we have been previously.

We have encountered this bug several times on our Minecraft Realms server. We have users playing on Switch, PS5, and Windows PCs. The user who has noticed this the most is the Switch user (but this may be because they spent more time around the animals). These animals all had nametags applied.

Using the World Utilities Chunk Border we did see that the enclosures from which animals have disappeared the most were on the intersection of four chunks. The animals were always noticed missing when the chunk was unloaded and then reloaded.

Probably not something you're too concerned about, but we also noticed any mob captured with a Safari Net from the World Utilities Add-On vanished after a seemingly random amount of time (one vanished a minute after release, others lasted multiple Minecraft days and loading/reloading the chunk.) I mention this only because the issues could be related or give ideas as to where to look for the issue.

In order to better address issues with unexpected entity loss going forward Mojang community mangement and the volunteer bug tracker staff have decided to resolve this report. We believe that random entity loss was fixed for most players in the 1.18.30 update by changes to how entities are stored in the world databse. For that reason, I have added 1.18.30 as the fix version in the report header.

We recognize that some players have continued to experience unexpected despawns. Resolving this report is not meant to dismiss your stories. Rather, it is to enable us to focus on information that is current and helpful for understanding and reproducing specific issues. If you have an an entity loss issue that is not explained by any of the points below, and you cannot find another open report describing the same issue, then you may make a new report. Please make sure to be a specific as possible and give steps to reproduce the issue.

Some of the cases described in comments here can be explained by intentional game mechanics:

Mobs that spawn naturally and have not been interacted with are expected to despawn, both at specific distances from the player, and randomly if they are old enough.
Mobs face dangers from the natural environment such as wandering into lava (some mobs do not avoid dangers by design), being struck by lightning, or being attacked by natural predators/enemies that can spawn near them.
Allays that a player has given an item will teleport out of enclosures to the player, and travel through nether portals with the player within a certain distance.

Some other recent comments here reflect specific, ongoing issues:

MCPE-143979 bees tend to wander off to the northwest
MCPE-167346 frogs suffocate under doors
MCPE-170425 mobs may teleport back to a nether portal when the terrain fully loads
MCPE-175546 mobs may come out of different nether portals than the player
MCPE-181306 paintings may break during loading
MCPE-183649 villagers glitch through blocks in certain orientations when getting out of bed
MCPE-186753 villagers or other mobs on positioned on chunk borders may glitch through blocks when loading

Finally, please do not comment here. This report will not be reopened.

That's stupid, I was playing a month ago, and sent in a video of when I was playing on a realm and an hour in, the villager despawned while I was inside the village after trading with him and moving on to the next villager.

I got dumb replies like maybe he changed jobs or maybe he died. After looking for hik for 20 to 30 mins, the villagers reproduced, so it could not have been a job change. And I was very close to the villager, there were no hostile mobs or hazards near the village.

Since this happens frequently with other mobs that are bred and named, I decided to add a bunch of more beds to increase the village population. A week later the villager reappears, the same one, with the same trade level.

Instead of calling it resolved, why not say we are not sure how to fix it at this ttime. Mobs dissapearing is very common, especially when playing in different chunks. I understand that in large worlds, chunks get unloaded and things magically don't get loaded back in when you go back. But when you're in the same chunk and it happens...

I have a 12+k day survival world and over the last week I have had 1 villager (named and traded with) disappear. He was trapped in a one block area linked to bed and workstation. I hvae just logged on and returned to the trading area to find 3 more have disappered - also traded and named in the same set up. I have been Afking for a while lower down and logged out, plus moved out of the area, so I am not sure when it happened. These were also converted natural zombie villagers not regular ones or ones that I forced into a zombie state. You can see the missing three [spaces] here. The villager marked [B] is the replacement for the other one. I have been losing villagers a lot in another trading area but I assumed they were somehow falling through the walls when waking up into the farm below as I had seen a couple in there. But now wondering if this is a problem with them just disappearing aswell. Bedrock v 1.21.51 Thank you Cjsgoose

Hello Shannon. It is really very disappointing to increase the level of a resident to lose him later, especially when selecting the exchange that we so desired. in an attempt to help, give some information.

Sorry for the really long list of info here 😛 This is the link to the video again - https://gofile.io/d/A0hGrx or https://drive.google.com/file/d/1haCHRTl9YCLKbYW0T2c6komcck82hDKY/view?usp=sharing

Reply from @unknown: documentation can be found here.

Reply from @unknown: Ridden entities despawning on relog is tracked separately at MCPE-51837. I've added a link to to the wiki section on finding chunk borders in the workaround panel.

Reply from @unknown:

Note from @unknown: the cats spawned because the game still considers missing villagers to be part of the village population until their 20 minute timer runs out. The missing tamed cats probably had been blocking cat spawns before the snap.

What you were doing leading up to the mobs disappearing?

single vs. multiplayer, local vs server/realm

how far you traveled

how long the current or previous play session lasted

whether the despawns were near a player spawn point or if you had changed your player spawn point during the session,

if you experienced lag or anything else abnormal.

Reply from @unknown: sounds like you are playing Java Edition. This is a Bedrock Edition report. You might want to follow MC-153904.

Reply from @unknown: I don't see how the report description could be any more global than it already is.

Reply from @unknown: thanks for mentioning that report. I'll see if I can get enough info to reproduce it.

Reply from @unknown: if you are not going to elaborate on your test methods and results, then this is not helpful comment.

Reply from @unknown:

Villagers keep disappearing (have not been killed, also not on a chunk border)
