A couple of posters are saying they aren`t getting any dragon souls.
I am pretty sure this is because they are re-killing a "burial ground" dragon. I think in the original version they did not give more than one soul.
I just re-killed the dragon at Ancient's Ascent. It was still a blood dragon. Then I fast traveled back to Whiterun, and a dragon appeared inside the town. This was an ancient dragon. The first one did not give me a soul, the second one did. So I think it is functioning as intended.
Also got a nice finishing move on the ancient dragon, :celebration:
