So I'm having "a bit" of a technical issue with my current savefile - everytime the clock advances to midnight the game freezes for several seconds (usually around 4s, randomly up to 10s). Other than that, everything works smoothly.
So far I'd tried a bunch of things to fix it and nothing has worked. I've restarted the game, but that obviously did nothing. I've removed everyone from Photo Studio, Carwash, Club, Camshows, I've greatly cleaned up the list of characters (down to ~50 actors), fired all of staff. The savefile got much smaller, but the freezes are just as long as they were before all of that.
Oh, and it's not a very long game either - it's the middle of september, year one.
Has anyone ever seen that and managed to fix it?
