Forum:Crawmerax Glitch Affects Drops?

Hello, I have killed Crawmerax around 20 times now using the glitch spot, with no pearls. I just wanted to check that people have gotten pearls from Crawmerax using the glitch spot (the one in the NW corner of the stage which causes Crawmerax and his minions to roar at you), and that I'm not wasting my time...?
