I've had no problems with the Pitt thus far, but I haven't finished it yet (I have almost no time to play games these day, sadly) but I also didn't finish the main story yet b/c of all the DLC I knew was coming down the pipe, and I've grown rather attached to my character, so much so that when the system didn't give me the achievement "Scientific Progress" for some unknown reason (I finished the quest, but no points for me) I didn't want to start all over to get it... maybe I should try to find that save game, I almost always make a new one... anyway, whatever, the point is... I want to get me some higher xp level, yeah... I don't know, I lost it there, sorry
