The Xbox 360 version of Batman: Arkham City is said to be costing gamers hours upon hours of progress with a save file glitch that's corrupting data. Complaints have filled a 21-page forum thread, indicating that the issue may be more common than is comfortable.
Problems seem identical across all users, with the game completely unable to recognize the file's existence. No trick or fix appears to be able to bring it back on the user end. Needless to say, customers are not happy about it.
Warner Bros. is said to be working on a fix, but there's no timeframe, nor confirmation as to whether or not the files are lost forever.
I bet the PC gamers are glad they waited.
