Some people have noted that the newly released WWE ’13 data has caused them to lose some of their saved data. This has affected both Xbox 360 and PS3 versions of the game.
Not only has it been resetting save data, people have lost their Universe Mode settings and as well as Superstar Threads data.
THQ has noted a few things you should do to prevent this from happening:
-Download and install DLC from WWE Shop menu.
-Return to the Main Menu and do not select any other options.
-Let the console sit for 10-15 seconds to ensure everything saves properly.
-Power down the console.
-Reboot and enjoy with saved settings and new DLC.
THQ is currently looking into a full solution to the problem. Until then, this should help you from experiencing any problems with the WWE ’13 DLC resetting your data.
