Man. You went wild there.
Though I have similar issues about little issues with quests.
WARNING:
Careful, spoilers ahead!
1) Was kinda Friendly on the druids side . Though was a bit curious and found out through a Note, that Rath has the last stone Rune.
2) Stole that from Rath and went to open the path leading down to a little treasureroom. Which, as good natured advanturer I left alone! ... Kidding I looted it all.
3) Some time later I snuck into the Goblin Stronghold.
4) Killed the Priestess and Mithara without anyone else taking notice.
5) Afterwards I casually spoke to Ragzlin who told me to help Mithara (who already was dead by that time)
6) I freed Halsin, killed Ragzlin and cleared the Stronghold.
7) Because I knew the camp outside was swarmed with Goblins I fast travelled to the Druid Camp.
8) Spoke To Halsin, he told me Rath would have a Reward for me... Well, seems he does not. Maybe I stole my reward beforehand?
So after all this I have 1 Quest that seems to be stuck:
- Raid the Grove. Probably because I already killed Mithara beforehand.
Whether Rescue the Druid Halsin may be stuck, I will find out
