Its no problem. After u left i tried to fight them off, and i managed to defend well (inspite of them farming our ai), and then guess what.... I crashed to desktop too. I think it is the same error as your crash.
Is it possible that someone from the enemy team forced us to crash?
How can 3 people from the same team crash 1 after another? Nobody in the enemy team crashed.
First our ally crashed, then you crashed, then me. All between 2-3 minutes in between crashes.
Coincidence? I dont think so
