I noticed the issue when swapping her out on my first playthrough. Everything on the surface was completed in a goodish fashion, and I hadn't traveled to the Underdark yet. A friend finished all content before he realized she was bugged.
- No interaction
- Tried reloading, restarting game
- Tried downing her, but not killing her
- Couldn't try prior saves because I kept her in my party pretty much all the time
