I had the same issue with Fate Worse than Death - nothing updated when I emptied the urns.
Also, I haven't been able to close out the Migo quest - I kill a creature on the coast surrounded by corpses named Migo, but when I return to the Magister, she demands proof. Which I never found ... maybe I did and sold it?
It was Migo's ring.
Ah, so it was - it was equipped, and didn't recognize that I had it till I unequipped it ...
