Reading this thread thoroughly makes me sad for Minthara. I was postponing my third playthrough for her. I thought with the new recruitment, or exploit? added she would be fixed by now so I decided to give it a try.
Romancing her after the act's finale she will say that tonight we are fully hers... but NOTHING ever happens
I just got this scene after going to Act 3... and yeah nothing happened. I romanced Karlach and Laezel before this and I immediately notice the change. With Minthara, she doesn't greet me differently. I can't even break up with her xD Not that I want to after all I did to get her, but the lack of option sure is strange. It's a big shame that her content is so sparse. I think she's a really interesting character.
