I was only able to get my world back by using my Xbox Live cloud save. However, even after redownloading the world, whenever I go to make a copy in order to back it up, it immediately freezes the entire game. If I override the game and go to my Xbox home and then try to reload the game, I am given the message that the game needs to be reinstalled. So I have reinstalled it twice, and each time I try to save a copy of the world, the same thing happens.

Same issue on 2 older iPads.
