Don't know if everyone has this issue, but the game seems to have a problem with various light effects sticking and becoming permanent. While this comes in many forms, permanant visual effects from spells, the glowing eye bug and whatnot, but the most common one for me is that the lighting effect on nirnroots will stick and sometimes even stack becoming quite bright. Simply picking the nirnroot doesn't make it go away like it should after it sticks. I fear that these extraneous and leftover light effects can slowly build up bloat and corrupt saves, so I would like to remove the glowing effect from nirnroot altogether until such time as the issue is fixed.
