Yesterday a friend and me wanted to play Dungeon Defenders after a long time. We created a character and lost the network connection. OK, my Steam friendslist was down too, I think that was the problem. After we start playing the game and did 2 levels, in the last wave we lost connection again... without any obviously Steam issues. We left the game and would try it tommorow. Now I was trying to farm some XP, but after 5 minutes I lost connection again.
So, whats the problem? Are the Trendy Net Servers are unstable, is it my connection or is it Steam? Usually I don't have any internet issues. So, this is very depressing and if it its go on we have to look for another game.
