After updating to 1.16.100, game runs very laggy. Often time blocks fail to update after placing to destroying. For examples digging straight down a column of dirt will occasionally respawn some dirt blocks above me after I've reached below them. Other times placing a block, I will see it immediately despawn and the item is added back into my inventory.
I've also seen villagers go to bed and once sleeping, they will hover to the west very quickly. Saving and loading times seem to have increased as well.
Thank you for your report!
