Hello! So, I have a question— I'm currently doing Ayn's route, and have reached chapter 6. I have done both those battles with butterflies and gotten perfect clear but for some reason the next chapters aren't unlocking themselves, and I tried doing those battles multiple times and nothing keeps happening for some reason. Does Ayn's story end here? Is this a bug or something? Do you know any way I could fix it?
