It works for me but I haven't played that long to fully verify.
All of features 1-5 work fine, dunno about the rest.
It does work, patch 6 only fixed a crash in MP.
Yeah, I tried it now and it works ok with the new patch, and I actually thought that it would be ok since it's only a mp patch. It's just the shock of seeing a new patch so quickly after the long awaited previous patch. I still say that mp patches should be optional from steam.
