This problem occurred on Friday multiple times. When I play local multiplayer split screen, after some time many in-game mechanics break. The problems I can recall off the top of my head are:
The block mining animation stops
Blocks cannot be picked up
The health and hunger bars freeze
All mobs freeze, including monsters, and stop inflicting damage
The map freezes
On one occasion, a player's avatar was moving while a copy of that was stuck somewhere
I believe I have the latest Xbox update.
