[L4D2] Official Servers Only in main menu can connect to community servers as well as Valve servers
In Left 4 Dead 2, the button in the main menu (Campaign > Quick Play > Official Servers Only) seems to connect to community/unofficial servers in addition to Valve servers. This seems to just affect Campaign, at least as far as I can tell. The All Servers button seems to act normally.

Duplicated by multiple previous issues. Valve knows this is a problem, and hasn't done anything yet. I doubt they ever will do anything. I doubt they even look here anymore
EDIT: Also, no, this doesn't just affect Campaign. This pretty much affects everything, including Versus. That's one reason why so many people complain about servers like Lewd4Dead.
