Brawler Archive

I don't know if this is limited to brawler or not but I experience pretty frequent crashes while I'm in combat. My game never crashes while I'm not fighting nor has it ever crashed while fighting with a pistol. When it crashes I just get sent to a desktop with no warnings. This has happened to me on two different computers on different internet connections and I have only noticed it since the spet 4th patch. Has anyone else experienced similar problems?
