I have problem with this quest line. He is the last drengr to finish the quest line. I was able to defeat him but I used the spartan kick ability for the last kill shot. Unfortunately, this launched him on to a wall mount and now i am not able to speak with him and finish off this quest. This the last mystery to be completed in Eurvicscire, England section and as well as the whole map completion. Please help :(...

The Drengr fight in Eurvicscire, NPC is stuck on ledge after using a kick ability on NPC to finish him off. Can't interact with NPC to finish of mystery quest. Tried reinstalling game and restarting game, npc still stuck. Please help, last item to 100% complete game ;(.....
