Hello. I would like to report that my world has begun to present several problems. Initially, villagers began to disappear inexplicably from my villages. Then the villagers who are left, sleep on the floor, in the air, or fly over environments. At the moment, creepers do not suffer damage from arrows, conduits do not work, inventory takes time to be accessed.

There are many problems. I would like to know how to solve this, because I created the world to play with my niece and built many things that now do not work. If it is not possible I will delete the game, because it was a lot of time lost.
