My siren is speced for cataclysm so when i farm things i phaselock them to get slag damage. Now when ever i do damage to slaged enemy i get the challenges for doing slag bonus damage and my badass rank goes up by 30000. I do not want to cheat but i have no idea how to fix this. I'm generally upset i want to play on my siren but i can't without glitching my badass rank and i like the idea of badass rank i do not want to just disable it. I assume i did so much bonus slag damage that the challenge backed up into itself, shouldn't they be able to fix this? I can't even play the game right now because of this stupid glitch.
