In episode 3, after one of the most emotionally intense moments of the game so far, I quit playing for the night. When I tried playing this morning for work, it looks like all my saves had been deleted back until the end of episode 1.
I'm playing on the xbox, and it looks like all my achievements are still there, up until I lost my game, the most recent being "handle it"
I was signed in to xbox live at the time of play, as well as when I was attempting to reload. When I load up the game, it says "connecting, and refreshing episode status" like normal.
I sure hope my game isn't lost for good, because I have no intention of starting all over again.
