textures crazy

I was playing the newest pe version of minecraft. I came to the village and suddenly my phone froze. When I re-entered minecraft, I was shocked! All over the world the textures of the blocks changed! The roofs of the houses were replaced by the texture of the lighthouse! And the texture of the grass was replaced by the texture of the door. But my things in the inventory remained the same. The texture of the ground was replaced by the texture of some green block. As for living creatures, I don’t know anything, because I didn’t see anyone alive. When I recovered from the shock, I took several screenshots. But for some reason out of 5-6 screenshots, only one remained (maybe I accidentally deleted them). I tried to get rid of this bug. I rebooted the phone 5 times, but the textures remained the same. In the end, I reinstalled minecraft and everything became normal.
