Batman: Arkham City players have been experiencing save data loss on Xbox 360 since the launch of the game. Publisher WB hasn't had anything to say regarding the extremely unfortunate bug until last night, when it published a survey on its official forum asking afflicted users for details.

In the survey, WB seeks information about the Xbox 360 model, storage method, and system software used to play Arkham City. If you can overcome the rage from having your save data randomly destroyed, please email support@wbgames with the answers to the questions listed after the break. It might help Rocksteady tune its cryptographic sequencer, which it will then point at a computer to fix the issue.

I was using a "phat" Xbox 360, running the latest release of the system software (not a preview), and had only the Catwoman DLC installed when I lost all my progress, in case anyone there happens to be reading.
