I've found this bug in release versions, and as of 21w11a, cats can still get stuck pathfinding toward a bed they cannot reach. (such as: a village house with the door shut)
Have this issue in Java 1.14.4 as well.
Directed at [Mod] redstonehelper in reference to MC-124460 vs MC-124508:
I CAN interact with things, menu items, entities, blocks, sounds play, etc.
The difference between my problem and theirs is they can SEE things changing, "The food bar will degrade, chat will show up and continue to work.", I cannot see, I CAN interact, it is as though a screenshot was taken and pasted over the window.
These threads are fundamentally different.
Dropping files...
Yep, all logs for the 19th say that OpenAL failed.
The issue seems to have automagically repaired itself.
Couldn't tell you how. ¯_(ツ)_/¯
My guess: Shouldered parrot animation is linked to player animation.
Solution: Isolate player head angle OR dismiss player leg angles.
I can reproduce it, this particular black cat runs all the way back to the glass house when manually teleported (see 4 new screenshots), and just stands by the wall, (yes the cat is mine, I checked, (ordering it to sit, then stand, made it follow me again)).
Note: only occasionally does a cat become so fixated on a bed that it forgets to teleport, (I had a whole group of cats here for a fair few minutes and only one bugged out).
Update: somehow I got them all stuck on the roof (picture 5), the roof is slabs and the cats are not teleporting.
