The Mysterious Woman that I freed constantly crackles as if she has a lightning spell readied.

It started after the first fight she got into and has persisted since, even when she has no spell readied or her hands are sheathed.

The problem seems to have resolved itself. Though it's worth noting that I've encountered enemies who, after I've slain them while they had a spell readied, their corpse continues to emanate the sound the spell produces.

And now she's locked in sneak mode whether I'm sneaking or not, which causes her to stray FAR behind me on my travels, practically disappearing until I enter an indoor location

This problem solved itself as well.

Both of these problems seem to return and disappear occasionally.
