I have the same exact thing.
What happened in my case is; I went to the castle, and found Halsin in the cage. He told me to kill all the Goblin leaders, I did that, and then killed the rest of the castle since they all got hostile towards me (this was not unexpected).
Since this took me some time to complete, I sortof forgot about Halsin, and went back to the Grove, where all the Thieflings are packed and ready, and all started thanking me for helping them. I spoke to Zevlor, and he said, there will be a party tonight at my camp. Sure invite yourselfs why not.
So I had a long rest, we had the party, it was fun and all, we had some drinks and we reminisce about the good old days, and nothing seemed out of place.
From what I read on this Forum, Halsin was suppose to also be there, but he was not, off course not, he was still standing in the castle minding his own business. So later I wen't back, he was standing there looking a bit lost. I told him "Snap out of it man all the leaders are dead". He told me "Awesome come see me in the grove or whatever", turned into a mouse and ran off. He never showed up at the grove.
I suspect the game did not expect me to go back to the grove and talk to the Thiefling leader before talking to Halsin.
