I updated the game and the DLC's on the itch app and then re-added the DLC's RPY files back to the main game and now everything's fine so far. I'll have to restart my character over again but this is no issue at all as this game has serious, serious replayability.
I'd like to say thank you. Thank you so so much for creating this game. I've never felt more seen and understood and acknowledged until I bought this game. As a demiromantic bisexual woman, too often I'm accused of sending mixed signals and not "being honest" with my chosen partner/crush, etc. There was none of those nasty feelings in this game and I sincerely appreciate it.
