After the update to 1.18.30/1.18.31 the game will freeze when the autosave feature is activated. If you’re playing with someone else, the player hosting will freeze, and the other player will get disconnected from the server. The worst part is when this happens, you’re kicked out of the game, however, you remain in the game and your environment is still active. For example, I was playing with a friend and the game froze. At the time, I was in the water when the game kicked me out. After I re-joined the world, I spawned in the water, but I was at the bottom and I drowned as soon as I joined. In other cases, zombies, creepers, and others have killed me while I wasn’t in the game.
