Okay so I have a question I have killed a dragon and I had seen it respawn a few days later, killed it but no soul. So do I not get soul for killing him again? I do seem to get souls from other dragons. Although I do believe I have killed a dragon and got the soul even though it was "Cleared" like the other. Any info on this?

Download patch 1.2.

I heard if you downloaded patch 1.3 then their is a chance you won't absorb any dragon soul if you on PC
