Aside from fixing pressing issues like "campaign image not updating correctly when creating a lobby" and increasing "the reliability of the Steam Group server display," Valve's recently released PC patch updates a crucial issue with Left 4 Dead's latest DLC: keeping doors closed. Apparently, during Versus mode in the game's "Crash Course" DLC, players were able to release teammates from "rescue closets," assuredly stopping rampant R. Kelly syndrome. The game may be fixed, but will that cure your urge to micturate on people? Only time will tell.
