Game ending glitch!

Level 17, chapter 6
Started game up to notice all the content was wiped out, vanished, gone. My game, everything! I was forced to download the 115mb of content all over again (which takes at least 45 min). Why did this happen? Hours of gameplay gone.
Up until this point I was really enjoying the game, a possible 5 star...but as is it will just crush you when it happens.
