Need some help with the GECK. I got for the most part the Quest working however whenever i kill the NPC the Quest marker stays on the dead npc despite i killed him. How do you make it so the quest marker goes to a different NPC The quest giver telling the player to go to that npc after he's finished killing the other NPC. The Quest works after i kill all the NPCs i report back to the quest giver and the quest can be completed with a dialogue option. However i'm just trying to get rid of the quest markers off of dead npcs. Any help is appreciated. Thanks.
