I've been bothered by the fact that in every Noggit version, we haven't been able to access the whole isle of Quel'danas. (The place over Silvermoon, where Sunwell Plateau is.)
It seems like one or two ADTs in Quel'danas is making Noggit to crash.
Try it yourself if you haven't, take 30 seconds of your time and load the zone. And you'll see it crashes.
Have anyone solved this problem? I would really like to access the zone, but it seems impossible with Noggit right now. :x
