So I was playing and was at about chapter 7, I think. All the time I had been relying on autosaves; when I loaded the game after exiting, I just selected "Continue Game" and I just kept on playing.
However, now my brother decided to start a new game of his own. When I went to "Load Save", all I saw were autosaves from chapters 1 and 2. I assume that since I never explicitly saved the game, my autosaves were deleted. Am I screwed?
