After I got the update, I found that I could go into a world twice, and everything was fine. But when I went in a third time, I could move around just fine, but when I broke a block, it took at least 30 seconds (sometimes up to a minute) to show the particles and to drop the block. Similar things would happen with chests and beds and boats, as well as the inventory. (I didnt test anything else, but Im sure it was the same for everything) I would click on a chest or bed, try to enter a boat, or open my inventory, and it would take at least 30 seconds for anything to happen.
I also found that mobs were frozen, sometimes floating.
This is happening to all my worlds, the game is basically unplayable.
