Since this post is all about quest/story stuff I've spoiler tagged it.
So, I'm on the hardest difficulty setting and I'm at the Dwarves of Dumathoin level. I've found one Amulet on the ground in the first area with the Dwarves, murdered the dwarves for the three amulets but alas I cannot find a fifth. I have scoured the map top to bottom, tapping tab the whole way just be sure that I'm not missing anything. I've scrubbed the map clean, there are no more items on the floor nor are there any containers left unpilfered. I cannot find the damn fifth amulet.
Is this some consequence of playing on the hardest difficulty or is this a bug?
