Hi guys, I just downloaded the v6.1 yesterday, if you want to keep your save files (I'm on PC), you can go into the old club detention folder -> game folder -> save folder. Copy the save folder and put it in the new club detention folder v6.1, Works like a charm.
Also if you are reading this dev, I love what you do, and i couldn't wait to have more content, I literally missed the game and checked if there were an update, which there was, lucky me =3
