I started a new game,and after a couple of days,after all the customers left,the day should end in theory,but it goes on forever,cant do anything about it,only reload the game,and lose all those days played without saving. My bad.
Out of the blue,the game says I dont have any money, "$NaN", so the game is pretty much over because of this bug. I had like 50.000$ before that. I think I was building walls right before this occured.
