So I got Deborah, and everything says Oskar should join automatically alongside Deborah, but Oskar hasn't. I even checked the SoD board that shows all my SoDs, and her star the Chizoku Star, is still vacant, and she's not listed anywhere else. I put Deborah in my party and talked to Oskar again, and she STILL hasn't joined. The SoD page of SuikoSource says she joins automatically and every guide I've looked at says so too, but she won't. Any idea if I messed something up or if my game glitched?
