Disappearance/despawning of mobs and entities that should not despawn

Mobs and armor stands that should not despawn outside of the simulation chunk disappear.
This occurs both in worlds on the realm and in worlds created on platform storage.
It is assumed that the cause is not despawning as a game rule, but because the data of the affected mobs themselves was accidentally deleted.
(Speculated from the fact that links to leads, beds, and workstations remain for a certain amount of time, as described in MCPE-21416)

Reproduction Procedure:

  1. Start play on the Nintendo Switch and discover the village.

  2. After confirming that the villagers, the Iron Golem, and the animals created as decorative livestock in the village are working properly, leave the village.

  3. After leaving the village, set up a spawn point about 1000 blocks away from the village and play Minecraft for a total of 12 hours while working.

  4. Then visit the village again.

Expected outcome:
Since there are no players around the village, hostile mobs that would harm the villagers will not spawn around the village.
The mobs belonging to the village do not act because they are outside the simulation chunk and do not, for example, fall from high places and get hurt.
Thus, the village is in the same state as when the player left.

As a result:
The village is empty.
Or, most of the mobs have disappeared and the village is deserted.

I exaggerated the distance and time, but this phenomenon also occurs when the distance is much closer and the elapsed time is a few tens of minutes.
(In such cases, the number of mobs that disappear is also small.)
No game crashes or network disconnections occurred during this time.

I have noticed this as well. Secondly, my named horses and a donkey attached with a lead also despawned out of nowhere. I can still the lead “animation”, or whatever you call it, on the fence, but when I right-click on it, the lead doesn’t pop out. Please fix your despawning issues. It is annoying and a waste of time. I had a diamond armor and a saddle on that horse, and a saddle on the donkey. Now, I have lost two saddles, which you cannot even make in-game.

I get the same issue. At least six villages in my world have completely despawned that way, In one of them there were villagers that I had secured in their houses and they still disappeared. So far it’s been an all or nothing for me, either the village is fully populated or mob disappears (villagers & golem).

I also had one named and one unnamed wolf that were sitting in a secure location that disappeared. It is a very annoying issue.

Hi and thank you for your report!

However to further investigate the bug we will need a world on which that happens.

Is this only or specifically happening to villages? Do any other mobs or structures are impacted by this? (e.g. woodland mansions or pillager outposts?)

This ticket will automatically reopen after you reply.

It's not just in villages.
It can happen to everything from livestock on farms to pet animals in houses to installed armor stands.

In the case of self-made bases, it often happens that a player goes off on an adventure far away and when he returns, some of the mobs have disappeared.
In the meantime, the spawn point is not fixed, as the beds are carried, set up, retrieved, and spent the night over and over again.

I don't know about the woodland mansions, but at one pillager outposts that was put off due to lack of preparation, the allay that was supposed to be in the jail was gone when I revisited it.

My own sense is that mobs and entities far from the player character or spawn point disappear at a higher rate and on a larger scale the longer the interval between visits.

This phenomenon happens routinely when playing Minecraft on the "Switch", regardless of play style or world.

Minecraft version 26.32 as well

I’m starting to believe that there is no real willingness on the part of minecraft to fix this issue.

It’s been years and I haven't seen even an attempt at fixing this.

I could not get the villagers to despawn even outside the simulation distance so perhaps it is fixed in the new update?

That is a possibility, although I doubt it. What is important to understand is that this isn’t a 100% repro type of bug.
I don’t know what you did to test, but if you just found a village then went far away and returned. That isn’t enough. Even in my game some villages would hold a bit and then eventually I returned and villagers would have despawned, Other villages despawned pretty much immediately. I feel that is an issue where time and numerous save/load have an impact.

I have a type of play where I expand a lot. I’ll build tunnels and corridors in the overworld and the nether to connect faraway places. I explore a lot to make maps of the area (like 8k x 8k areas and sometimes more).

I understand it makes the issue harder to test and pinpoint,so I understand it,s not easy to fix. My impression is that it is a bug related to how they changed how animals and other things spawn and despawn compared to how it was a decade ago or so.
Anyway, I can’t say if the issue is still there since I haven’t played in a while, but from what I see from other players there are still some issues that are in the least, very similar if it’s not the same bug.

You are probably right, I did the test with my own villagers in a duplicated version of the world where they went missing. I stood outside of the simulation distance for a few days, then went to check if anything had happened.

It's unfortunate because now I can't trust the world anymore if they have a random chance of disappearing
