MInthara's romance is pretty easy to dynamite by accident and then you get the whole "You are bold to seek me out, after sharing your affections with another!" silent treatment loop.
I think it would be better if she would interrupt us immediately and call us out, either while it's happening or right afterwards. Instead of waiting for a camp interaction, since the player can progress quite a ways before realizing and it's annoying to backtrack in Act III where there can be a lot of cutscenes and story progressions before grabbing a room at an Inn. I wasn't sure if it was a bug, but then realized it was the Rapture incident that got under her skin. Backtracking a few hours is always tough, when people would probably just reload sooner if Minthara put us on ice right after the interaction, the same way she might chime in for other plot related line delivery.
