When finishing the first chapter, the only endings that work are the Helen, Valentine, & Sigma endings. I've maxed out the 5 hearts for Mei & Susan but neither of them work. I have the latest patreon release. Do I have to go somewhere specific to find Mei/Susan?
Also, can I max out the hearts for more than 1 character during the champion segment, or do I have to only max out a single character for it to work?
