Hello,
I've updated the game to fix some minor issues.
Services output from commercial buildings have been increased by a factor of 25 to avoid rounding issues with low outputs. Correspondingly, the demand for services has been raised for residential buildings.
I've also found goods output from industry to be a bit low, so that has been increased slightly.
Lastly, a bug where the small police department and fire department were marked as upgradable has been fixed!
