I too am unable to kill the leech.
Killed the blacksmith, he gave me a marker for the leech, and she's active in my Order screen.
I go to the marker and she never shows up.
When I track her quest in the order screen and then try to highlight it (with the brackets on the map), the quest marker disappears altogether.
I then have to reactivate tracking her in the Order skill for the quest marker to reappear.
I have no old saves to go back to.
Hard stuck on this main story mission, please provide a fix asap.
