Good game. One question with Catherine, is she supposed to appear in the Harem? I played that event that said she was added to the Harem, followed by an error message, and then Catherine is nowhere to be found. On another event right after, she is back in the mutant camp being given the vaccine by the MC.
She'll not appear untill passed the color test (not implemented yet). However the error message is worrying. You can load the screenshot in the discord channel: https://discord.gg/DJgeurX6JY
