Well, I had 1 golden key I've been waiting to use till I'm lvl 50.

So, today I get on and load my game up. Get a notification that I have 11 unused golden keys. I was like WTF!? I pulled up the challenge menu..... On top of getting 10 golden keys for nothing I also had 55 badass tokens. My badass score went from around 4 or 5 thousand to over 10 thousand. Crazy. Don't know why it happened either. Anyone else have this happen?
