Hi redblade1530.. To solve this problem you need to build more houses. Homeland battalion can exceeded just means that you don't have anymore place in your city for units or even resources that you buy through the market. Hope it helps and you can contact me ingame as well.
Ps: Royal dragon needs 15 space - Red dragon needs 12 space - Green dragon needs 8 space.
