SPOILER AHEAD:
So since i like the possibility of going down evil paths and am really looking forward to how far down that road you'll be able to go(pretty far so far^^) i though i'd raid a druid grove with my new drow pal, as you do.
However, now that i've cleansed the Grove of the tieflings and druids(most of which were dead alread cuz i attacked Kagha when i met her) Minthara seems to be stuck and uninteractable. She's chilling in the "secluded chamber" Zevlors hidey hole just standing there talking to herself about our lord and saviour the absolute but i can't talk to her and any action(perusing her pockets, a friendly nudge) to cajole her into doing something results in her attacking me. She's a jumpy one that one.
I've tried resting, warping and reloading. If there's a cinematic supposed to start once the grove is cleared i did not see that one. Might be relevant as i've seen similar issues were had for other people who somehow skipped cinematics.
Obviously if anyone has a fix for this it's welcome greatly otherwise it'll just have to serve as a bug report and i'll have to go back a few saves
