Villagers sleeping on the ground or sideways or not on a bed but when waken up they get out of bed and walk away.

Villagers including villagers with jobs randomly stopping and not being able to trade or hit or interact with them but they still make hmm noises. Basically ghosts and they dont move. Multiple affected at one time but theres still other villagers that arent affected.

Hostile mobs being invisible and attacking. ive experienced it with a skeleton, and a slime that was visibly stuck in one spot jumping but when i got close but out of reach it still somehow hit me.
