WWE 2K17 officially released today and I am having a ton of fun with it, however other players are noticing that there is a very nasty bug in the PS4 version of the game. Some users on Twitter and Reddit have mentioned that if you put the console into safe mode while you are on the main menu, you run the risk of the game erasing ALL of your save date. Not just your WWE save data, but ALL of your data on your PS4 hard drive.
No word if this damages the data in your cloud but to be on the safe side, do NOT put the console into rest mode when you are playing. If you are done playing WWE 2K17 just close out the entire application to prevent this from happening. Tickets have been created and hopefully 2K addresses this immediately.
