Are there actually 7 clues in the goblin camp? Because I can't find more than 6, and I've checked the map several times and found no more sparkling spots or NPCs. It doesn't seem to prevent the quest from completing, but it's weird the counter says "6/7" and the daughters basically go, "We've got all the information we need!" anyway.
Edit: Also, I cleared an area with daughters (can't remember which area) and an NPC with a star over their head appeared in the planning room with a scene where ambassadors from the other Drow cities showed up, but it referenced clearing out the Sahagin which I hadn't done, so I decided to do that before activating the event to do things out of order. Except by the time I finished that, the NPC had disappeared but left the star floating in an empty void, unable to be interacted with. Is my save just borked?
Edit Edit: Well, I think I figured out what caused the second issue, so consider this a bug report: If you walk on the tile that starts the Zeknet conversation (Which wasn't sparkling at that point), even if you haven't talked to the guard that takes you to the Quarstra lecture that should precede it then the Zeknet conversation will trigger. Then the Quarstra conversation will trigger out of order, and while you can complete the resulting quest fine it apparently messes things up so that the Palace Guard NPC just won't actually appear anymore.
