My brother and I were having a game and it seems every time i am doing something and he's flying around with the elytra my game crashes and becomes un-playable until I copy the world and re-open it. It sometimes works. The error code is Data corrupted. sometimes loading back into the game it says problem opening and won't load. 

this error was only apparent after the hotfix for ps4 bedrock edition it seems. 

I was just working on structures and opening shulker boxes and he was trying to explore and make maps by flying around. we have done this before this update and it seemed to work fine.
