Yesssssssssss!
That did it. You're the best. Super, super appreciate the help. I was gonna be pretty bummed if I had to give up the whole run - I haven't played BGII in ages and I was really enjoying the nostalgia.
She still won't talk to me if I do a force-talk, but maybe that's not a thing in ToB / you're not romancing her? It's been a while since I tried.
She moves and detects traps now though and frankly that's enough for me at this point
There is not very much from her side in ToB if you do not romance her. She has no PIDs at all in ToB. So yes, she detects traps and has some interjections with people you meet during ToB. As long as she has no further bugs, that is about it.
She seems to be fine now. Even had that bacon conversation about ~10 minutes after I used that file.
Thanks again for your help!
