Thanks...
My biggest complaint now is how leaving the game, then coming back destroys a well functioning city. I had a city doing great, $20k in hourly income, plenty of water, sewage, and power.
I exited the game which saves the city and came back an hour later...
All of a sudden I need more water and sewage, not just 1 extra pump but double capacity for each. I have a maxed out police precinct well placed but crime goes up dramatically for no reason. Casino starts losing $5000 a day- the warning the education level has fallen to low so the nuclear power plant melts down.
The city that was $20k net positive in now $5k in the red within a few minutes of resuming.
Stuff like this happens almost every time I resume a city.
