After installing "Dragonborn" DLC, two people came and informed me about the Dragonborn in Whiterun, and then attempted to kill me. So after whooping their buttocks I continued with the game and around two weeks of in game time has bassed, but everytime I visit "Whiterun" their corpse are just lying there.
I'm assuming this is a glitch considering the bodies normally disappear after your next visit.
How can I fix this problem?
