Forum:Is Crawmerax "tired"?

I don't know if others have noticed this, but lately farming Crawmerax the Invincible has gotten friends and me lesser riches than previous times. I have gotten around 3 orange guns and NO pearl guns per kill. With a large party we get the same amount of orange/pearls, this is just depressing. Is there some unknown fix for this, or will I have to kill Crawmerax 100 more times to get a peice of pearl weaponry that I have a better version of as is. Please I would like to know, I don't mod, and I don't hack, and today I killed Crawmerax 7 times (with a party)! Please help me with this,

P.S. Sorry if I don't post this in the right spot (I don't understand it 0_0)
