I recently got this Harley Quinn's Reevenge dlc. After I completed the first mission as Robin, I got a screen on which it said "Two days earlier", and the saving symbol was shown. This went on for almost 5 minutes, then the game crashed when the saving symbol was still displayed. This corrupted my save file completely. Now whenever I try to resume the dlc, the game exits to desktop with an error. Now there isn't even an option to start the dlc from the beginning because whenever I click on the dlc, it attempts to resume the corrupted save. How can I start the dlc from the beginning? If I do, then how do I prevent this crash from happening again? Thank you.
