one more feature(doesn't have significant effect on the gameplay): avg. quality in the "Studio chart" tab in the general info can NOT be large than a single quality of a product. Currently it looks like you calculate it in some nontransparent way, but this effects year bonuses only, and therefore can be lived with.
After reaching slightly more then 2.000.000.000 in bank all my money turned negative and I ended up with -2.000.000.000.Is it a bug with the variable type?
