Ok, so above Riften and under Windhelm is this area of swampy/dry land sort of. (dunno the actual name) There is a dragon wall there with the shout words for frost breath. I killed this dragon there and he never like disssolved to let me absorb is powers. No other dragon has ever done that, and its only that specific dragon. I went back, re-loaded a save, and fought/killed the dragon again. He never dissolved. He just lays there twitching. Has anyone else encountered this glitch?
