having either a chest or enchanting table and returning to it after it has been unloaded becouse you were tofar away makes the animated model freakout in the position it was in when it was unloaded. chests when opened will have both a closed and open lid en enchanting tables will have 1 or more closed books vibrating above it aswell as the normal opened book.
bug only apears after it has atleast been loaded and unloaded once.
Have you tried f3 and A? Thats the only advise i can give. Sorry 😞 I hope it gets fixed soon 🙂
