I'm gonna cry-

I spent hours yesterday leveling up the school on the final level (I don't remember what it is, I'm from the UK so I don't understand any of the school side of it) and I maxed it out graduated and everything, I go in for like five seconds, and it resets the whole thing. And I don't want to redo it and spend over six hours on it. Do y'all know if its a bug that will be fixed and give progress back or do I actually have to spend over 6 hours doing it.
