Does anyone know if the corrupt saves issue is really bad or has been resolved? Was going to start playing but there is no way I am going to risk it if it's screwed. Losing save progress will really piss me off.

Was thinking about picking this up but can't figure out if it has campaign cp-op. I have read multiplayers stuff is coming in December and there are special co-op missions but nobody is clear if they will add campaign co-op or not. Anyone actually know?
