Hey you know that the game runs the same time like the real world right? And at night your people get too tired if you keep making them work and you get frustrated putting them in bed again and again. Well here's a way at night to make their energy bar halfway or more without sleeping or an energy drink! It's the most simple thing ever! First go to menu and press settings. In there there will be a reverse day or night. Remember this is only for real night time. Press yes and then it will be daylight. Then leave your little people and wait at least 1-2 hours then your family will keep increasing energy.
