These glitchy dragon skeletons really are something. I killed a random dragon (Viinturuth) near Windhelm, and the dragon bones and scales I looted from him made me overencumbered. Against my better judgement (having tried this before) I stored some of the enchanted equipment I made (but didn't need except perhaps to sell) on his skeleton, made a savegame, and fast-travelled to Whiterun to store away my bones and scales. I have over 40 Dragon Bones stored in a tiny cupboard, I can almost build a house out of those things.
Anyways, I return to the site where I killed him, and his skeleton's just gone. Slightly disappointing perhaps, but I shrug and move on. I come across a small cave with Dwemer machinery apparently going into the water of a stream, a Stormcloak camp (who I can't kill without incurring a bounty for some stupid reason), and a Dwemer ruin. As I'm ascending the steps up to the Dwemer Ruin, I kill a fox to absorb its soul. I turn right, and see something big moving in the corner of my screen. I quickly draw my sword and turn around, anticipating a fight with a troll or something bigger...
But it's Viinturuths skeleton, glitching through the ground and settling in a strange positions. He apparently really wanted to give me my items back.
