Has anybody had this? I see it in the game under my feet ever since I completed the Dawnstar nightmares quest with Erandur (I think it is). Haven't seen it before and now it wont go away. It seems to randomly grow and shrink as I walk along. Doesn't interfere with gameplay but it's a little distracting. It looks a little like a sideways helmet made of ice. I call it the Phantom Ice Helmet. Haven't installed any new mods lately. In fact, I had to disable the Dawnstar Overhaul mod which makes Dawnstar more like a proper city because Erandur couldn't figure out how to get out of the modded town so he could lead me to Nightcaller Temple!
