UPDATE: Apparently, only cheaters have been affected by downloading the new character in Borderlands 2, so download away and mechromance, my pretties!
ORIGINAL: A word of caution, Vault Haunters!
Installing Gaige the Mechromancer comes with a glitch where you lose not only your Badass Ranks for all your characters, but your Golden Keys will reset to one.
Looks like Gearbox Software jumped the gun releasing the much-desired Mechromancer a week early. Twitter is abuzz with gamers desiring their stuff back, and it looks like this glitch is affecting players across all platforms.
