Family Centers:
Once a Family Center has been placed on the World Map, it's default construction status is 0 with a durability of 20%.
In order to begin construction, Family members must garrison troops at the Family Center.
The default priority is the increasing of the building's construction status. Once this has reached 100%, begin working on durability. Once durability has also reached 100%, garrisoned troops must remain and continue to defend the building.
It's important to keep in mind that if a Combined Operation is launched against you during construction, any troops working will stop to come to the defence of the building.
Only when a building's construction status reached 100% will members begin benefiting from its effects. If at any point, durability reaches 0%, the building will be destroyed.
When a Family Center is upgraded, the benefits it offers are also enhanced. Even if a building is destroyed or located, it's class will be protected.

Family Resource Stations:
Once a Family Resource Station has been placed on the World Map, reserves are defaulted to their maximum.
It is not essential to construct this building immediately has dispatched troops can perform a similar collection function.
Once a Family Resource Station has collected all available resources, it will disappear and await a family elder to decide on a new location.
When a Family Resource Station is upgraded, its reserve limit and collection speed are also enhanced. Once a station has disappeared, it will retain its previous levels.
