I am SO frustrated right now I cannot see straight. (I'm feeling like an unbalanced Balance right now!) I got through the maze and defeated Grettir and his little friends BUT I couldn't find a way out without losing my progress. Since I didn't want to go around in circles anymore trying to find my way out I had to lose. Will somebody please help me?! Thanks in advance!
Once I beat Grettir I don't recall ever doing anything but teleporting out to Northguard. I've certainly never retraced my way through the maze.
Winterdeep warren and Helgrind warren are a little strange in that once you defeat the final boss of the instance, Jotun's brothers, they stay beat even if the instance closes. The exception is if you team up with a player that hasn't beaten the brother, then he comes back as long as that player in in your group.
