Recently I tried loading my world on Xbox one, I've done a lot of work on it and it was fine until a few days ago when I last played it, the only thing that changed was I invited someone on to the world. The next day the game gives me the message "There was a problem loading this world" this is the second world for me to have this happen the first is now corrupt and I'd like to get this one back if I can, any help would be much appreciated thanks.
