About 3 times I have increased my population by 1,000 citizens, had more than enough money nd was unable to purchase improvements There appears to be a bug that is preventing me from buying infrastructure. As a manager or administrator I assume you have the ability to closely examine my game activities. Feel free to look up how often I have purchased improvements in the past couple of months versus my population and available dollars. You will see that I have added thousands of people and millions of dollars and yet have not purchased improvements. Please let me know what you find out.
