I talked to her the first time and it must've bugged out because she did NOT appear at Moonrise. That's what made me reload my save to redo everything all over again. I got it to work by not talking and destroying the war drum. It is a total hassle. Not to mention my character has no reason to knock her out and leave her there...

Larian devs, if you're seeing this, please give us a cutscene and the choice to spare her instead! She's also becoming one of my favorites.
