I have what seems to be the Draugr glowing eyes effect, but it persists after adding/removing the draugr abilities spell (F71D1). It is not any other spell, I checked. The effect is most apparent when strafing because there is a blue glow trail that follows the eyes. To clarify, I entered player.addspell f71d1 in the console, exited/reentered console and entered player.removespell f71d1 multiple times. No mods are causing this as far as I know, I checked that too.
