They probably don't even read this board since it's not the feedback board, you don't see people discussing this stuff and getting up in arms on it on twitter/discord/reddit like you do with Karlach or Minthara so as far as Larian is concerned it's not even a problem. Hell, nobody has even made anything about it on their feedback forum on their Discord. I would but I'm not articulate enough to make a big write up on how shitty this being in the game is.
I created a thread in their feedback channel on their discord, in case you guys want to reinforce it, it's called "Shadowheart Romance Inconsistencies" (yeah, I know, not the best title, I'm not perfect with words, but hope that will be enough). I didn't go as deep as we did here, but you could keep commenting things there, and hope for Larian to see it.
