I am already Thane of Windhelm, and Torbjorn's wife has committed suicide, and I have a Rare Gifts quest stuck in my list, i.e. "Bring one Amulet of Arkay to Torbjorn", which he is supposed to show to his wife (now dead). Despite having two in my inventory, he will only speak non-interactively to me about drinking, or his wife (sometimes saying something that indicates she is still alive). Any hope of clearing this quest? This is on the 360.
Update: It turns out one of my two Amulets was flagged as stolen. Once I dropped that, he accepted the non-stolen amulet.
