I posted this in other forums..not had solution yet.
The problem is getting into the Harper place in the docks for the second time..
I been in once to do the Montaron quest. Jaheira left my party, came back the next day. I have been attacked by the bandits (where they take Jaheira hostage...) and i have done the poisened man bit. Jaheira now says that i need to urgently go to the Harper Stronghold again, but i cant get in. The door is locked and is unpickable (or bashable). There is no-one standing by it to talk to either.
Is there something i need to trigger to get in. Cant think of any other way of getting in.
