Personal Assistant

Your personal assistant is here to assist you in all city-related affairs. You start with one Personal Assistant, and should you need another one you can get her in the shop for a modest price. Each Personal Assistant allows you to build/upgrade your buildings and/or technologies for 8 hours before she is overwhelmed with her tasks. When they are overwhelmed, you cannot give them any additional tasks until they finish all of their current assignments. When one Personal Assistant is overwhelmed, the other will be ready to assist you. When both are overwhelmed, you have no choice but to wait for them to finish.

Personal Assistant

Example : Personal Assistant A is tasked to build the Palace which takes 5 hours. Since the total is under 8 hours, she can do more tasks. Then you asked her to upgrade the Market (2 hours), which takes the total to 7 hours. Then you asked her again to upgrade the Farm (3 hours). Since now the total time on her is 10 hours (>8 hours), she is overwhelmed and you have to wait 10 hours before giving her any additional assignments.

Personal Assistant B is then ready to do your assignments. You asked her to upgrade the Palace (8 hours) so she become overwhelmed straight away. Once both Personal Assistant are overwhelmed, you must wait until either one of them recovers to continue building/upgrading your city.

Note that any upgrades are done instantly once you ask your Personal Assistant to do it.
