The Duergar woman did not give potions at the begining like she says in the dialouge. Also, there were no potions in the fern at the end.

Additionally, the duergar woman doesn't take the trophy from you at the end.

Is it alright if we just shoot the duergar woman and get a new one? I'm so sick of her not doing what she promises.

But what about the children?!

Well, in the children quest the lever pull doesn't register so you can't finish it. Also, apparently you can save the little girl if you're fast. Really fast. Like faster than the group I was with, which tore through the foes without any luring or much downtime at all.

Update on this, please. Has this been fixed?
