So, I am in a store looking at the clerk and I turn around and then the clerk had somehow teleported to sitting at the table... What the heck!! Scared me at first

Saw this once. First glitch I've seen, 12 hours in.

I assumed that something happened that made the game not want to put the NPC exactly where it 'made sense to do it', and had to choose another spot

Well it only happens in gerdur's house in riverwood, now that I checked

Hope they fix this!!!!
