I am near the end of Blades Quests. I have brought 3 followers to Sky Haven Temple and talked to Esben, got the blessing and he has sent me off to Dragontooth to slay the dragon. When I arrive at the crater, the three other novice blades are there and we head up to where the dragon is waiting. It is there but not attacking. I get his health down to 0, but he does not die and the followers start attacking way off to the west near Bthardamz. I can run off chasing the ghost dragon, but never find it and when I come back the Blades are there waiting for me again and we can turn this into a Ground Hog Day.

I have killed this dragon before and activated the word wall, so this might be a source of the problem.

I have waited to see if another dragon will appear or if I am sent to another site to kill a different dragon.

Nothing seems to help. Any suggestions on using console codes to bring this dragon back to life or is there another solution?
