I'm having trouble with a very odd glitch. I was outside Riften and there was a Dragon flying over head. It flew away after a while and then I went inside the city. But then I noticed the corpse of a Dragon inside Riften, with it's skin on, just sitting there. I could search it, but I could also walk through it and couldn't move it. Now, whenever I fast travel anywhere, or load a save outdoors, that same Dragon's corpse is there. Does anyone have any idea who this glitch is, how it was triggered, or how to fix it? It's getting very irritating.
