Ya know, I had actually assumed it was fixed since they released an announcement saying they had fixed it, but after a quick google search and a gander at the Steam community, it seems a lot of people still have issues. Though the reviews for the game are still very positive (even with Steam's new 30-day review system in place), so I think they've cleaned up.

That said, the game itself unfortunately hasn't changed much as far as content goes. Lots more mods, but I haven't gone through the effort to see if my friends and I can even play modded maps together. That would be amazing because I've played to death the vanilla portion of the game.
