So... since you also posted the other question related to old saves, I'm assuming you are using old saves. Which are the cause of most problems, and properly also this one. I have tested that route myself several times and "it should work". No other reports.... So, I would highly recommend a fresh game.Thanks! It had me worried for a second, lol.
Not trying to be a bother and keep spamming problem after problem, but I am having trouble with Sato's route. After completing the drunk scene and going to the job afterwards it the game somehow freezes at a black screen. Not sure if its my save or something. I will include my save file just in case.
Or to start you off with, here is a save from day 10 where the game splits up. Town hall = sato route, Or go over to melvin's cafe for that route.
