Well now the romance suddenly triggered.

So we had
-> Have Dammon repair her heart, she 's so happy and says she'll come to me that night. Next camp rest, Mizora cutscene happens, no Karlagh coming over.
-> After this camp the option to tell her what I'd like to do with her disappears from conversations.
-> next camp : nothing
-> one or more camps later : Lae'zel wants to fight me and then make love.
----> If I consent, Karlagh gets jealous and tells me I treat her as a toy.
----> Id I don't consent, no change.
(I continued the game not consenting and effectively breaking the romance path with Lae'zel)
-> More camps follow with no change. I didn't count them
-> Then "boom" out of nowhere, she has the exclamation mark when we enter camp. Says she'll come to me that night and she does.
-> Now we have a "kiss" line in conversation.


I have absolutely no idea what triggered the romance. It was a camp like any other and nothing special happened during game play earlier. Before and after the trigger, approval rate was max.
