Same thing happens to me on Halo as well. PSO isn't to blame on this one. I'd like to know why as well if anyone can tell us as I have to redownload a game that took me 22 hours to download to begin with.

Like the post says. Anyone have any idea why this happened? This isn't the first game on the MS store to do this to me and it's getting annoying since I actually like this game, but I won't redownload it a 3rd time if this happens again.
