You can try this
Put the attached file into BG2EE/override
Load a save from before you put heart and body into the altar, then try again.
If it does not work, you best post a save game here (after you defeated Bodhi + before you put the things on the altar).
That did, much obliged. She was red for like, half a second, then turned blue and I could talk to her. Seems normal; I'm going to run through the rest of her quest now, hopefully it'll be smooth sailing from here.
Just to satisfy my own curiosity, what did that override file do, exactly? Just kind of like, blanket-reset for where all the variables were supposed to be, to fix whatever happened to be borked?
