Actually, the game does this when a world is corrupted. I got a pop-up in-game when I tried to load a world and it told me it was corrupted, then automatically deleted it. So, it sounds like your worlds and characters may be corrupted and automatically deleted, but you aren't being given a pop-up. That is my best guess.
