Colony ships and supply

[Kjara]

Since colony ships function without supply, if you start one building on a planet, then lose your command center, it continues to build.  Great for that moment when you realize you uncovered your command center and are going to lose it, but  have the troops to hold the planet, but probably not intended.

It's okay with me -- that's true for any directly-built structure that doesn't require supply.
