It's hard to picture what you are saying in that lump of text sorry.
It sounded like you said that you could not leave the room with Halsin, but then you said you had the camp party, for that it means you were able to port out to the Druid Grove.
Which door is it that you get Halsin's dialogue? Are you locked to one room? Can you move?
You wrote "as soon as I enter the goblin camp". So that means you can run around. Can you enter Priestess Gut's room? Can you enter the puzzle room?
