I have created two seperate houses in FA2 YR.
Actually, I have four customs

Dominator House
Beacon House
Left Yuri House
Right Yuri House

The last two dont appear ingame, though they are created the same way as the first two.
A screen below, the structures and units (miners) do not appear ingame.
The other two do. Dominator house has been created for power purpose only. And Beacon House is easier to change to the player then using Change House...
They have all been created with power purpose. It would look bad if the left base would have gone out of power, and the right one too.
