I started a new file, I am about 20lvls in, and just began the Dawnguard quest line. I was out in the wilderness, about to fight a bear..and went to transform into a Vampire lord. As I did, My character was stuck in the crouch position after his body starts to morph (silent hill esque) as he stayed put in stance, he was lifted higher, and higher, and higher, overlooking skyrim..hagard and bloody, unable to move. At this point I set down my controller and waited for him to drop to earth...to his untimely death. But to my suprise after a minute or two of a choppy decent into the sky, once he dropped he landed safely on the ground on the other side of Skyrim, and finished his transformation.

.....erm. Anyone?
