I can't wait for that update then, I know they're busy doing other games and focusing in another characters, but I really like Alice and Japan, I don't like Adrian that much, for now I'll just stick with the trying to befriend him with playing games, I'm not going to be manipulating files because I'm dumb and I know I'm going to break it for sure haha, but thanks for your response!
Honestly it's not that hard at all once you understand how to save file works. but yes if you want to play safe just choose for him to Stay, not leave, and after some time it will unlock itself but just don't forget to pay him a visit on Tuesdays. I also think that talking to him when Josef takes everyone to camping helps too but not sure to be fair
