It is not technically a bug or anything so important but why there isn't a trigger which end those quests when you kill Grutilda? Now I'm stuck with a list of incompletable quests (Star-Crossed Lovers, Back-Alley Trader, The Armory Key. Even The War Stone remains in the quest list if you kill Jarhl.
That's just the way Larian has chosen to do it... if you break quests by killing the owners, the quest wont close but instead haunt you forever.
I can somewhat understand it (having seen the logistic nightmare it was in another game promoting 'you can kill everyone') though... even if it's annoying on the player's POV.
