I play practice sessions much of the time.
Overnight, I'm unable to change settings in Greed and Betrayal; when I try, I'm kicked out of the game.
Also, when, for example, I add the Titan mutator to Deathmatch, it also shows up in Greed. I've uninstalled and reinstalled both the game and the 2.1 patch. I've purchased a new UT3 game but have yet to install it.
Any ideas what's going on?
