I thought it might be related to her turning into a Cleric of Selune, because the game says she's now empowered by Selune (in the dialogue after the Nightsong), but that's certainly possible. She went through a lot while leaving the Shadowfell, Shar did not hold punches based on how she explains it. The pain that poor girl suffered just to be with Tav (and to rid herself of Shar's influence, of course).

All the more reason to believe the inconsistent interactions should be removed/changed, I'd say!
