Ok, first I would like to say that this bug came into play mainly in the 1.16.101 hotfix, but it was still there in 1.16.100. 

Whenever I’m playing Minecraft, the whole game crashes and the app just closes out. I can double click home and it doesn’t show it was recently used. This may happen one time or maybe even ten times. I know it is not just my device because my sister will start playing w/ me and her game will crash. I have no clue how to replicate and it seems pretty random. Another important detail is it will put you back to the place you were a number of minutes ago leading me to believe it has something to do with data saving. Please fix this as it will make a better game.
