Yeah 2 trophies didn't unlock actually during the system error thing - "Made in Fyrestone" and "Discovered Krom's Canyon". After everything started working again I logged into the game, no trophy dings yet. I zoned into Krom's Canyon and that trophy unlocked right away but the other didn't. Since there doesn't appear to be a way to replay previous missions I'm out of ideas on what to do other than complete the game and redo all the Arid Badlands missions over again. But for now, I don't think it's going to unlock for me. I earned quite a few new trophies last night though with no problems.
Was good playing MW2 with you haha told you I suck nuts but I was loling pretty hard when you were telling that kid to stfu his voice was pretty annoying, I had to mute my mic so people couldn't hear me haha
