An unlucky few though, have had their Badass ranks reset due to a nasty bug. This bug also causes these players to lose their hard-earned skins that have come from unlocking Badass ranks, while at the same time keeping challenge progress unchanged. Unabated, this means that those affected are unable to redo the challenges which awarded them the skins in the first place.
Gearbox had this to say about the issue:
“At the moment, it seems to be a fairly rare issue and we’ll keep you updated on when we resolve it.”
The bug occurs on the PS3, 360 and PC versions of the game, meaning that no one is safe. It’s happened to people in single player and multiplayer games, with many people reporting the occurrence as splitscreen players. The bug has been narrowed down to profile data corruption. Gearbox has said that it has technicians on the case.
One way to avoid the bug or at least recover from its effects is to backup your save data multiple times. Since the corruption occurs in your data, it’s wise to keep a copy for when the skag hits the fan. Steam users can find their data here: Documents\My Games\Borderlands 2\WillowGame\SaveData\.
A player by the name of RyogaWanderer has video of the Badass rank reset as it occurs.
I can say that I haven’t had this happen to me yet but I will be holding off on the game for a few days in case a fix is found before I need it. To everyone out there, stay safe and stay badass.
