I used three quest maps at once. One of the quests worked fine. The other two don't activate when I walk on them.

One is just next to Joffrey's Army, the other a bit north of Procipinee's.
Also, when I went through the Namtur-thingy one item (the temple) didn't activate when I walked on it, just disappeared. Also, that one could use a boss, I think, though the "clear all the pits" idea is pretty cool.
