Under Main Quests, Find a Cure, the quest 'Rescue the Druid Halsin' is still active and hasn't updated.
It says to Talk to Zevlor, however, I already have and have had the party.
Halsin is in my camp, and I've played a bit more since. However, I just noticed the quest hasn't updated in the journal, and I'm a bit worried about this.
The tieflings have left, and there is no marker on the map. It's just in the quest log.
I have played the Alpha as well, and there was a small cutscene of Volo singing (which wasn't finished at the time) when you have the party. This also didn't happen, but I just chucked it up to this being the full release and things being different.
However, now I'm a bit worried some flag may not have trigged?
