I believe there is a drop rate bug, i've talked to a few coder's who said this source has a small glitch.

Okay, so everything was going smooth until i put on my hellacious cape for 98% DR now i go dry every where even sponge bob, I killed around 30 and didn't get a drop, And before i got 98% dr i was getting a drop every 2 kills consitantly, I've encountered this twice before on other server's, one was the result of packet loss on the server side, And the other time there was a glitch happening between the rare drop tables and % drop rate changes where if you had % drop changes like rings it wouldn't let you access the rares drop tables anymore, until it was fixed.

hey mate i am having the same problems!!!i have 68% dr and i was at customs with some new players and 1 of the player had 20% dr only...he was getting drops every single kill while i wasnt even getting any drops!!I hope the owner fix it soon
