I wanted to try Rasaad, Neera and Dorn's quests at the nearly end of the game, before returning to Candlekeep (Chapter 5).
I've finished Neera's quest without problems, without triggering her at Beregost until Chapter 5.
I can't do Dorn's quest, because the first time I encountered him at the Nashkel ambush I refused him, now he's at the Friendly Arm Inn but can't get him in the party or start a conversation, the only thing he says is:
'You'll see the errors of your ways soon enough. Begone'
Have I advanced through the game too much? If so is there a way to do it anyway? I don't want to start another game all over again.
The ambush at the docks doesn't trigger in the Rasaad's quest, I've had the two conversations with him and then tried to trigger this ambush but doesn't work.
I've also tried travelling back and forth through the map to let the game time pass, doesn't work either.
