The game runs perfectly fine with no D/C and 0 lag when I'm not in The Wolve's Den.
However, I usually d/c with 90000 error at least once per match in pvp.
The game doesn't lag or freeze prior to d/c's, it just black screens and 90000 error.
My internet is completely find because I'm still on my VoIP program talking when the d/c's happen.
I've already tried all the basic troubleshooting, closed all other background software running, etc.
