I think the same thing happened to me after PSN Plus automatically patched the game. I started up the game and it went right into the intro sequence. Thinking I must've skipped past the "load game" thing or possibly hit "new game" accidentally (highly doubtful), I exited and tried to load up my previous game but the save was gone. Was it overwritten by the "new game"? Or did it disappear during the patch? I don't know. Is there only 1 save slot? Not sure if I want to play through all over again since my gaming time is limited these days. Very frustrating.
