Cities dont grow on their own
A simple mod that won`t allow cities to grow if you`re not interacting with them. You need to either satisfy store demand or spawn passengers, any amount of satisfaction/spawned passengers will do.
Uses Harmony to prepend a function to the City.Grow() function, making it so that it wont run if there`s no store satisfaction AND no passangers are spawned.
Should be safe to add and remove from saves, but as always backup backup backup!!!
