My phone is an Alcatel Fierce 4, Andriod 6.0, all mobs in-game have lost very body part except their head (sheep, cow, players), feet (chicken), tail (phantom) and a few others, everything else in the game works well, no lag, loading is as fast without the beta. To start the bug, I simply create a new flat, infinite world in creative on a normal difficulty with the "Experimental" mode switched on and I press create, after it loads normally, game running and loading chuncks, but all the mobs bodies are missing except for the head, including the player's skin.
