Act 1 Find a Cure potential spoilers

Rescued Halsin
All 3 goblin leaders killed
Halsin returned to the grove
I returned back to the grove using waypoint - Zevlor interrupted me and I chose to go to the party later
Met Halsin and completed the cutscene with him booting out Kagha
Met Rath and completed obtaining items from him (therefore completing Save the Grove)
Now, went back to Zevlor and spoke to him so I get transported to the party
Did the party - next morning Halsin automatically spoke to me
Exhausted his dialogue, and spoke to him again, and looks like the same dialogue prompts that I already went through - impossible to exhaust the dialogue
Quest still says "Speak to Zevlor." - but Zevlor is nowhere to be found, sub item also says to discuss plans the next morning with Halsin and similarly this doesn't get resolved too
