I read all the bugs on the internet related to this quest, but it looks like this is a very uncommon bug. While doing this quest i fed morkvarg his own flesh and finished the quest like that, I never even talked to Einar to complete the quest. However later while i was travelling around in skellige I came across Einar and talked to him, killed him and his men and looted the cursed fang. Now that morkvarg is dead talking and killing einar had no point however this for some reason brought the quest back up on my quest list and i cant get rid of it. The quest is under secondary quests but everything is checked and theres nothing to track. I noticed this after doing some other quests so now i dont have an older save where i didnt talk to Einar. Latest save i had was right after the combat with Einar's men started and i tried killing them but not looting the item but that also didnt work . So is there a way i can abandon this quest or am i just stuck with having that in my quest list ?
