I somehow got into a state where Lae’zel couldn’t be interacted with. I’ll put the rest in a spoiler tag for those that don’t want to know the details.

Lae’zel woke me up during the night and challenged me to a fight because she couldn’t stop thinking about me. She was down bad, lol. Anyway, I agreed and killed her dead, then revivified her. Well, that broke her. From then on I couldn’t talk to her, couldn’t interact with her at all, and she wouldn’t join combat.
When I got into a fight, she remained outside of the fight and could act with impunity. I was literally able to take control of her and go up to each enemy and kill them dead without using any turns. This is obviously very broken. So beware.
Luckily, I was able to resolve it by loading a save from before the fateful event, and only lost an hour of progress.
I tried through multiple saves to get her working right again, but no luck so in the end I just reloaded a save from before the fight and I since I wasn’t keen on continuing the romance anyway (It happened by accident in the first place) I turned her down when I redid it.
