I have updated the list of reported symptoms in the bug description based on everyone's additional information, and I'll continue doing this as we understand more about what's happening. If you see anything that you're sure is incorrect, please leave a comment telling me about it.
It's now clear that this issue has a lot of similarities to what happens to villagers in MCPE-101202, but for now we'll keep them separated because much of what the villagers do only happens when they sleep, and these other mobs don't sleep.
Bernard: Are you saying an entire herd of animals freezes simultaneously? If so, do they all become active again and move suddenly and sharply when you get closer? I think that's normal, or at least it's not exactly the same bug as this. This bug should only happen to mobs individually, and just moving closer wouldn't rejoin their split aspects.
DireCubey67: Your comment prompted me to revise the description. Hopefully now you can see that it actually is the same problem.
Miguel Guthridge: Thank you. I'm just going to add "and more" to the list of affected mobs, because once the number and variety of them reaches a certain level, it's best to assume it can affect any of them.
Mark Fekete: Being killed by an invisible mob is certainly what this report is about, but losing all your items isn't part of it. That must be a different bug, but you haven't given, and probably can't give, enough details for us to describe it well enough to be able to reproduce it. If it happens again, you should search for a bug report that describes your experience, and if you can't find one you should create a new report for it. The Bug Reporting Guide can help you with that. Unfortunately, there's no way to recover your lost items. If you don't have a backup, I'd recommend making it a habit to back up your important worlds every time you finish playing for a while. (Every platform's backup capabilities are unique; I don't know what's possible on yours.)
Lukáš Fireš: I think I had that wrong in the description, please check it now. Regarding separate coordinates, the server and client components of the game run in separate processes and don't directly share data space, so each has to have its own copy of the mob and player data (and a lot of other stuff). The components are designed to keep their own copy updated in parallel, so normally they would stay in sync, but even when there's no bug they can get out of sync far lots of reasons, so the game is designed to make the server send updated information to the client at critical times, and the client is supposed to use those updates to replace whatever I has in its records, thus getting everything back in sync again. Looking at this bug from a technical standpoint, it seems to have broken this built-in correction process in certain situations, most likely random ones.
c c page: That's the first clear report I've noticed of something like this happening to non-mob entities. Thus, I'm not sure at this point whether it's a manifestation of this bug or some other one. If others can confirm it or report something similar, I'll modify the description to incorporate it. In the meantime, your comment is available to the developers.
Everybody: Thank you all for staying focused on using comments to add new information. At this time I think we can do without further comments just to add new platforms or mobs as they all seem to be affected. I would like to have reports for any other entities, though, and of course anything of significance that hasn't already been reported.
I've started getting this issue frequently since I updated to v1.16.100. I've noticed it affecting cave spiders, villagers and iron golems. I believe it may occur with other mobs as well.
I can reproduce this on v1.16.201, Windows 10.
Instructions to reproduce:
- Load the attached world: Sky Lands.mcworld
- Run the command:
- Observe the following:
- Breaking blocks produces no animation or sound
- Breaking grass blocks with long grass above them does not break the long grass
- Commands fail to run
- Unloaded chunks won't load anymore
- Exiting the game causes a freeze on the saving world screen
May be the same issue as
MCPE-109119?
