Maybe it's just my copy, but after getting the game, I played through each story mode a few times, then when I tried again it skipped straight to the end, where Darkseid is imprisoned in the Netherrealm or Shao Kahn is in the Phantom Zone. I ended up deleting my profile info, which also cleared out all the saved endings, and went through Story Mode again. And now, as before, when I try to play Story Mode it skips straight to the end again. Is this supposed to happen? I don't want to delete everything again. Hopefully there isn't a limited number of times to go through Story Mode.
