Okay, so here's the thing, The blades ordered me to kill that ole Dragon, but I used the cheat setstage thing, it came worked, but months later, esbern came to me out of nowhere and ordered me to kill that dragon AGAIN, I came to the Throat of the world, and found the place he normally be, but DEAD, as I approach him with J'zargo, I found that he really is DEAD, how could he be alive if I absorbed his soul?
