I've got Stenvar as a companion right now and I just killed a dragon in Riverwood. Immediately afterward though I noticed him dragging himself slowly along the floor through the crowd of NPCs... at first I thought it was a little sad but I figured he'd get up again so I went on with the rest of my errands, but then I realised that he wasn't getting up and was crawling slowly along after me even though I'd entered and left a bunch of different buildings already... I'm pretty sure he's now doomed to be crippled for the rest of his life. Guess I'll have to fight that dragon again.

Anyone else had this or am I just special? Because I couldn't find anything on it when I looked it up.

EDIT: I fixed it by reloading... *relief*
