KuaiKuai keeps your buildings functional
Explanation:
Whenever a building is about to break down, KuaiKuai will activate and prevent the breakdown.
Each KuaiKuai can prevent breakdowns up to 5 times, and it will expire after 60 days.
When it expires or runs out of its uses, KuaiKuai will vanish.
You can place a KuaiKuai Spot from the Furniture menu.
It can only hold KuaiKuai and will display its effective range.
After completing the KuaiKuai Food research, you can craft KuaiKuai at a cooking station.
