This morning I tried several times to finish the skill point quest for Darkshade Caverns and Veteran Darkshade Caverns. Every time I reached the point where I had to talk to the NPC in the Hive Lord area, I would see the quest marker, but I could not interact with the NPC in any way that progressed the story. In the veteran mode, I was not able to interact with the NPC (which I believe was on the floor in a pile of dead bugs) and in the normal mode I was able to talk to the NPC in that room, but it did not progress the story, instead she just said something about murdering me.
Every attempt was in a Group Finder formed group
In Veteran Darkshade Caverns, we could not interact with Grobul after our first wipe. We had to disband.
All group members doing the quests confirmed that this was happening to them as well.
