Does any one have this bug? When trying to start a fist fight quest in ACT II -Roche, the screen turns black; this quest doesn't start; and no picture only sound effect.

Yeah, I got this bug too. Funny thing is, I was able to do it before.. then I reload an old save because I wasted money on something and figured okay, whatever I can go back and re-do this. Except everytime I re-load the game and attempt to fist fight the Blue Stripes I get a blank screen and sound, it's annoying.
