She has an invalid posture which is odd. Have you did the mod dance to see if the issue subsides without them?

On an issue like this, I am not sure if I would know how to conduct it. I would have to know how to duplicate it and I just dont know where to start. It was such a bizarre occurrence and I've had the exact same mods for months without it happening so, I imagine it would take a long time to reproduce. I tried the same scenario where she was under influence of the potion, napped and woke up but it gave her a different skill than the one that was associated with the disappearance.

I meant load the save where she's gone with just these mods. Does she reappear?
