I ran into a bug when I was doing "THe Blessings of Nature". I am about level 32 and I was in White Run exiting the house you can purchase. I talked to Adrianna as she passed for a moment and clicked out to go to my map. I then fast travel to "The Atronach Stone" so that I could walk to "Eldergleam Sanctuary" and get the sap from the tree. When the game loaded at the stone, there was a dragon in the distance who begins to attack. As soon as he does, every animal in the wasteland shows up red on the mini map (including the friendly ones). Anyways, I killed the dragon and when he died, there were still enemies around not to mention the absorb dragon soul sequence didn't trigger so it just laid there dead...

Not sure if you have run into this before, and I just reloaded ran around white run and fast traveled to a different but still close location and it seemed that everything turned out ok...
Hope that helps, if not sorry for rambling.

I had same thing where dragon didnt absorb but this was at a word wall i had already done before. i killed the new dragon grabbed its loot but it didnt absorb. then the treasure chest was restocked and the word wall made the music as if it had a word to learn but didnt do anything. dragon is dead chillen and not burning into a corpse dragon

Yeah, I got this one to work, but the Dragon Burial ground near Azuras Shine didn't absorb for me. But haven't had any problems with Dragons since (even frost dragons, which was the type of dragons that were fought and bugged).

I noticed this glitch as well! I would say its good to know I am not the only one this happened to.......
but I want my Dragon Soul! This has happened three times ( that I remember) is this a thing? You can't claim a dragon soul if you killed the previous dragon
there?

I don't think so man. If you see or fight a dragon, you should be getting there soul. If the dragon is at the same burial site of a dragon you already killed (and you even get a radiant bounty quest for it again) then you should definitely get your soul.... In short YOU'VE BEEN ROBBED!!!
THe only thing I can think of is that you shouldn't be able to get another dragon shout off a wall you already got one from....
Just a bug pure and simple... Thankfully, it doesn't mean that you wont ever get a dragon soul again, but in a Skyrim world of bilingual ascended reptiles, monolithic skeletal landmarks, and the need for a Dwemer custodial "Sphere"(named Rosey, from the Jetsons); an actual dead and decomposing dragon tend to stick out!

Also just wanted to do my duty as part customer part game tester and post my bugs!
