[MCPE-66678] Crash when entering the Nether and End after entity goes through

Summary:
The game crashes when entering a nether portal after a certain amount of mobs have been sent through.

Steps to Reproduce:

Create a world.
Create a nether portal.
Enter the nether portal and come back to the Overworld.
Spawn 15 or more mobs and send them through the nether portal.
Enter the nether portal.

Observed Results:
The game crashes when entering the nether portal.

Expected Results:
The game should not crash when entering the nether portal.

Original Description:
Game crashes to desktop upon entering the Nether. This has been happening consistently since the new beta release.

Edit: Seems to happen, in my case, after sending baby villagers to the Nether. The next time I try to enter, the game crashes to desktop. Then, when I reopen, I appear in the overworld about 10 blocks to the northeast. Always to the same position. The first time it happened, I loaded inside of solid blocks, and had to break my way out to avoid being suffocated. After several times of this happening, I was able to go to the Nether, as normal, only to discover that my baby villagers were nowhere to be found.

the issue happens mostly when an entity enters a nether portal before the nether is loaded after opening the world. You can fix it by using an external program currently to kill the item in the nether

I think this might be caused by the same entity issue as my MCPE-66763. In my case, it occurs when I send monster mobs into the Nether, as part of a farm.

I'm here from a duplicate issue that I filed. Will post my info also!

For me, this crash happens when entering any nether portal from the overworld. It seems to have started when multiple entities entered the portal in quick succession. In this case, it was two villagers that ran into the portal from the overworld at the same time. I can't actually see them in the nether database, but the items and entities that went in before and after them are in the database.

I have been having issues with items disappearing when they enter the portal simultaneously with a villager. Namely, I was bringing villagers into and out of the nether with minecarts; when I broke the minecart in the nether portal, both villager and minecart vanish. When the minecart fell in just before the villager, it also vanished.

I was using a portal with a wall behind it and found that my items and villagers vanished every time. After digging out a space behind the portal, at least one of either the villager or the cart would appear in the nether. My final solution was:

Make a room that the villager and cart could sit in that was behind the portal
Break the cart away from the portal
Pick the cart up
Push the villager into the portal

This seemed to work better, until I had those two villagers escape and jump into the portal at the same time.

I'm investigating using Universal Minecraft Editor (UME) to see if I can get the portals working again.

Using UME, I found that six cats entered the portal separately and turned out fine.

Again, the two villagers that ran in after the cats are not in the database.

After that, I threw in four emeralds and those seem fine as well.

Edit: Looks like deleting all entries from nether limbo fixes the issue

Jayson Durkee 2020-04-02T06:19:06Z

Nether limbo?

I have had the same thing happen as part of my guardian farm. It doesn't need to be many mobs, but they will crash the world upon entering the nether in their radius. Upon getting it to load after some lucky attempts, all of about 200-300 guardians vanished.

itszelace 2020-04-03T23:44:48Z

@Jayson Durkee

You can use an external editor like MCC ToolChest or Universal Minecraft Editor (both are not "officially supported" tools). Navigate to the "Nether Limbo" within the db and you can delete all of the entries in it.

Jayson Durkee 2020-04-04T23:19:28Z

I have done that, but it doesn't fix the problem. None of the mobs I send to the Nether end up there.

胡新锐 2020-04-05T05:54:58Z

After several villagers enter the lower level portal, the player breaks down when entering the lower level portal.

胡新锐 2020-04-05T05:56:34Z

After clicking the command, sometimes the typing box will block the vulnerability of the input box after clicking the input box

Tibor Tálosi 2020-04-05T06:19:22Z

Here is what solved me:
I've deleted every region except where my portal is (because I don't want to rebuild my blaze farm) and deleted every villager in that region using MCC ToolChest

胡新锐 2020-04-05T06:23:22Z

This vulnerability must be fixed!

Ahed Gardaizi 2020-04-09T19:28:37Z

This probably explains why it happened after half of my villagers went missing

Danny 2020-04-10T13:45:39Z

having the same issue on Xbox one beta, my nether portal is open to villagers at all times my nether has 20+ villagers inside, I leave it open because so many villagers spawn in my village, but I’m guessing now it’s the reason my nether is not working, please fix soon as please.🙂

Ahed Gardaizi 2020-04-11T20:12:50Z

I’ve tried several times myself to go back to the nether in my survival world, and still I am unable to enter without crashing

Guillermo J Colom 2020-04-11T22:14:15Z

A workaround if you don't have world edit or want to play strictly in survival:
Travel travel in the a few thousand blocks away from the affected nether gates. Place a new nether gate and enter into the Nether. Travel within the nether back to your affected area. The mobs that caused the crash will likely have "disappeared". Personally I travel 5000 blocks because I have an Elytra and I read that number on a forum post, but I suspect you only have to travel beyond the simulation distance (within nether).

Example, if you set your simulation distance to 4 chunks:

4 (simulation chunks) x 16 (blocks/chunk) x 8 (overworld/nether) = 512.

Of course it might be determined by render distance, in which case, if you have it set to 32 chunks:

32 (render chunks) x 16 (blocks/chunk) x 8 (overworld/nether) = 4096.

UPDATE: Tried this method after updating to 1.16.0.57. Game crashed while in the nether and was approaching the affected nether area after successfully entering the nether at a location 5000 blocks (overworld) away.

弹星者 2020-04-15T13:53:03Z

I have the same problem. That was when I get to my guardian farm for xp, after stay at the right position for them to spawn, I get into the nether portal, then the game crash down. I enter the game again, adjust to peaceful, set the simulation distance to 4 chunks, and get to nether from another portal. I successed in getting in to nether, but failed to get close to the positon related with guardian farm. Whenever I get close, game crash.

Jayson Durkee 2020-04-15T23:12:26Z

Why do you keep changing the title? It is a crash to desktop.

Dave Fritz 2020-04-19T00:10:22Z

I built a villager breeder that sends baby villagers immediately to the nether. A few things have been happening (1.16.0.57):

The first time I tried to go to the nether after sending a bunch of baby villagers the game crashed to a white screen and closed. When I reopened I was being suffocated in a bunch of blocks right behind the portal I tried to use. This has only happened once so far
Only one of the baby villagers appeared in the holding tank I built in the nether
I tried to breed more - I sent about five to the nether. I was able to travel to the nether but only one additional baby was in the holding tank
I have found that if I send one baby at a time and immediately follow that baby to the nether that baby is there. It has not crashed since. If I send more than one only one will appear.
All other baby villagers I have sent through have disappeared (other than the five I've immediately followed). I have not used any other software to check to see if the entities are still listed there somewhere.

Not a game-breaker yet, but definitely tedious.

Jack Johnson 2020-04-19T23:12:34Z

Oof, whenever I try to enter the nether, it crashes. I enter the portal, it does the loading screen, but then it immediately closes out of the game.

John Francis Bello 2020-04-21T09:43:36Z

It's not just with villagers but also with any mobs, passive mobs for my experiences at least, that went to the portal and crashes when you go to that portal or load the chunk of that portal in the nether

Jayson Durkee 2020-04-21T16:36:21Z

That's correct, John. I meant to update the original report. I should note that other entities seem to go through without issue, and that mobs going from the Nether to the Overworld just disappear, but do not cause a crash.

MythicBurritoz 2020-04-21T16:53:40Z

Jayson, unfortunately I crash when item entities cross through a nether portal as well, however it only happens once and the item does not disappear when I make it through.

Guillermo J Colom 2020-04-21T17:22:17Z

I send Strays and zombie pigmen into the nether and it consistently crashes. Usually three or more makes it go bad.

Jack Johnson 2020-04-23T19:46:27Z

I've tried this with chickens. When I created a new world on creative, I sent a few chickens in (I don't know how many) and it crashed. Also I went back and forth from the over world to the nether. I don't know if this will cause it to crash, but what I do know is that if you send other mobs in it crahses. Sucky thing is that I can't enter the nether in my survival world. The nether has a lot of necessary resources.

Antonio Mantella 2020-04-23T20:41:49Z

This needs to be fixed soon, because of this bug I am unable to get any of the new stuff from the nether and can not experience any of the new nether update in my survival world I can't believe a bug preventing players from accessing the nether has not been fixed when the focal point of the update is the revamped nether.

Jack Johnson 2020-04-23T22:54:19Z

So true, I thought it would be their top priority....

Jayson Durkee 2020-04-24T12:35:40Z

Just confirmed that the problem still exists in 1.16.0.58 Beta.

Antonio Mantella 2020-04-24T20:06:03Z

I wasn't even trying to make a nether farm, I just had my portal in the open and some cows must have gone through and even if I go through the nearby ruined portal the game still crashes so I think this makes it so you can't access the nether at all. It's such a surprise Mojang ignored this for 4 versions.

kmb600 2020-04-30T19:07:02Z

still present in 1.16.0.59

Jack Johnson 2020-05-01T02:58:58Z

It's been about a month now, idk what's going on, but I miss the nether. I can't get more netherite, can't find bastions, can't barder....etc.

Genome Editor 2020-05-02T20:07:14Z

Somehow I avoided this issue until version.59. Now I’ll be trapped outside the nether until it’s fixed, I guess. 😔 Well

Gergo 2020-05-02T23:20:40Z

The bug just occurred at me (1.16.0.59 beta) without having any villagers/other mobs enter the portal besides myself. I might have overdone 15 entries tho

niall 2020-05-04T03:38:44Z

just updated to beta and put like 5 villagers in and now i ant use the nether

Jason 2020-05-04T15:29:01Z

This bug should be a high priority bug due to the fact that it makes the nether almost inaccessible after this occurs and breaking many farms.

niall 2020-05-04T20:36:52Z

plz i quit the beta because my survival world is broken due to this

Jason 2020-05-07T16:18:50Z

Still affects beta 1.16.0.60.

Jayson Durkee 2020-05-08T12:58:40Z

Something seems to have changed. I have sent several mobs through the Nether portal. When I go through the portal, the game isn't crashing, but only one of the mobs has made it into the Nether. I have done this several times with the same results; several mobs go into the portal, but only one comes out. There are no limbo entries in either the Overworld or the Nether. It would be helpful if more people experimented and posted your results.

Guillermo J Colom 2020-05-08T14:02:30Z

I wouldn’t be surprised if they are working on it, but won’t consider it resolved until every mob sent in is accounted for on the other side.

Dave Fritz 2020-05-08T16:11:15Z

The problem I have been having for quite a while is the same as Jayson Durkee - originally the game crashed when I tried to enter the nether after sending a bunch of baby villagers through a portal (it put me into a space already occupied by solid blocks when I restarted). That hasn't happened again, but if I want to breed villagers for use in a farm (iron farm, trading center, etc.) I have to send one baby in, follow it in, and then return to the overworld for another baby villager. If I send in more than one between my visits only one will actually make appear in the nether. If a wandering trader, cat, or some other entity slips in before the baby, the baby won't show up, only the entity that goes in first - similarly, if a wandering trader and a llama go through a portal only the one who went through first appears in the nether. It seems to always be the first mob and only that mob. I haven't confirmed the other direction, although somehow magma cubes are coming out of the nether into the overworld periodically

MythicBurritoz 2020-05-09T02:34:22Z

It seems to depend on how many mobs go through now. Around 20ish mobs and i was able to go through with no crash, though only one mob went through. Around 100ish mobs and the game crashed yet again.

Darren Westlake 2020-05-11T14:47:00Z

Beta 1.16.0.60. Game crashes repeatedly going through Nether Portal irrespective of entities passing through. Using an 8 x world file backup system to roll back to try and work out cause/trends. Game crash = full game crash and not crashing to game start menu.

Observations:

1) Single mobs can go in at one end and not appear at other (havent tried multiple). Examples are horses, villagers, etc. Random; sometimes success, sometimes not. Sometimes game crashes, sometimes not.

2) Game crashes 1½ seconds after entering Portal on OW side. World file size is around 180MB. Seem to get more crashes after 180MB is exceeded. Game runs a compression algorithm after saving (nice btw) but not sure if world size is a factor as regards crashing.

3) Multiple events: Redstone circuits (permanent on), auto composters (while working), comparator clocks, etc seem to cause the game to crash more when entering Nether Portals.

After a crash, reloading the world that crashed - causes one or more mobs to disappear from the world, villagers in hall, sheep in pens, etc forcing me to delete world and use backups. Some mobs that disappear are on chunk boundaries however, other mobs that are also on chunk boundaries NEVER disappear (non nametagged)...HTH

Darren Westlake 2020-05-12T14:30:57Z

Update to previous:

World in previous ticket became unable to enter Nether through main base Nether Portal (Portal 1). Game crashed a dozen or more times trying to travel through this portal. Travelled in Overworld to different base and used NP there no problem (Portal 2). Travelled in Nether to the corresponding NP that was synced to Portal 1 in main base and found a stationary cat with its tail poking out of the portal tiles. The cat left the game abruptly (through no choice of its own) and haven't had a problem with my world since in the last 24 hours (fingers crossed). All cats in my main base have been tamed and sat to avoid further entity problems whereby if I reach the cat cap no more will spawn.... HTH

MythicBurritoz 2020-05-14T16:06:06Z

Appears to have been fixed in beta 1.16.0.61. Sent over 100 guardians through a portal with no crash when entering to the nether and all guardians made it through.

Jason 2020-05-14T18:48:38Z

Can confirm that it was fixed in beta 1.16.0.61.
