My game is acting very strange.

When I try to change settings in Greed and Betrayal, it kicks me out of the game completely.

Also, when, for example, I add the Titan mutator to Deathmatch, it's also added to Greed.

I've uninstalled and installed the game and same with the 2.1 patch. I've even ordered a new game to see if that will solve the problem.

Any ideas ??
