After completing the tech... buildings are building "faster" with less people. However the Easy Management doesn't autocorrect and assign the amount of population to the task correctly.
Easy management "10" expecting only constructing 10 buildings (Still uses of 1500 population)
Buildings page: "our builders will work the best they can in order to build 12 buildings per day"
PS. Would you like me to posts bug like these (new thread) or in the pinned "Backlog"? For future reference
