actually it is at 1.16.100 but there is no 1.16.100 option.
The bug is mob freezing, the mob is still running behaviorally but it's not like that on the screen, the mob just doesn't move. It's fine if it's just an ordinary mob (it doesn't attack the player) but if it's a monster then the monster looks like it's not visible and attacks the player without the player can attack it. can it be fixed?
