While I understand that there may be alot of work to do when it comes to bug and patch work, I fail to understand why the change from killer bee to Animal Pain (of course it would be the worthless version).

I have checked as many sources as possible: videos, players (Memo, Scion) and none of them have verified that Pain was first and then it was switched to Bee. Their words (not mine) were that it was always Killer Bee as a reward. So why the change? I have no idea. As in the words of the announcer from the Tootsie Pop Commercial:

"The world may never know."
