Yes, just keep progressing and you'll eventually get there, it just takes patience
Cool, it just happened for me. "Karyn was added!" prompt, and I see her. It was honestly giving me worry because I'd put many hours into my file before getting the latest version, and it didn't update to show I was missing Relationships with new girls added, so I worried my file wouldn't work. At that weird precipice of whether to start over or not, and wanted to make sure I wasn't just wasting time. I really appreciate your response, I'll make sure to upvote you all for helping me, each comment. :D
PS: any idea which girls I need to deliberately seek out to get added, or are there spoilers to be concerned with (Yuuka for instance, I hope)?
