!@#$. The game is glitcher than I thought. I wiped some guys off before one of the quests and now I can't kill them because they are already dead... The arrow is still pointing at the dead body with a missing head.
Hmmm unless it is an essential quest, it should have changed the to be killed person to someone else.
OR you simply go back and explain they are already did. Already did that with a SPOILER: Dragonstone Tablet from the first barrow etc
