Ok so I'm working my way through the challenge book, and I am on the streaking one. The bar is at 88 seconds from when I started the game. I did it just now for ages and it still says 88 seconds.
I'm level 50 and have pretty much all upgrades. Am I doing somthing wrong?

Are you actually starting the streaking mini-game? I believe you have to hit up on the D-pad twice to start it.

Are you pressing down on the d-pad twice to start the mini game?  Just being naked doesn't count.  Sorry if that seems like a dumb question but it's the only thing I can think of.

Ok so I figured it out, it says I had cheats enabled when I did not. I never entered any cheats do it seems to be a bug, loaded up an autosave from earlier and works fine. Weird.

Maybe the DLC patch had something to do with it.

Did you play any co-op? If the person you joined with, or the person who joined you, had cheats enabled it corrupts your save with them.
