I see it most often with wolves, but it's happened occasionally with bears, bandits, and (weirdly enough) Grelod the Kind. It doesn't affect all wolves/bears/bandits (though I haven't been able to hurt Grelod with either PC that I'm playing), but sometimes a creature will get a pale green glow, and nothing I do to it will hurt it. (Any creature affected can be killed using the console.) Grelod does not get the pale green glow until I draw my hands out to attack her. (I can crawl around her room and she looks normal. But when I pull a weapon or magic, she starts glowing. If I put my hands away, the glow goes away.)
It's happening with 2 separate saves using different (though similar) mod set-ups. I have other saves, but have not played them enough to see if they have the same problem.
