note: This NOT a dup of MC-50339 so don't just 'resolve it'. The details of the behavior are very different other than the 'won't sit' part. By flagging everything as a dup based on trivial similarities, you foul up the debugging process by hiding information from the developers.

description:

some standing tamed cats will suddenly not sit when commanded. sitting cats will stand and then refuse to sit. Kittens will not sit when bred.

Restarted server and client. Issue persists. Dogs behave normally.

There were no changes to the version, nothing changed about the player or player ID. Dogs are fine. Cats WILL stand up but then refuse to sit. Some cats may stand/sit while others will not sit.

I have checked the save files and all the cats have the correct UUID set as OwnerUUID so this is not a corrupt/incorrect UUID problem.

Update: I've gone further and confirmed the entire entity data structure of working and non-working cats seem to be fundamentally the same (i.e., there's nothing obviously broken for the bad cats). Could this have something to do with position in chunk data or something upstream in the data tree?
