Searched for these issues, and found nothing.
On a planet, that has, say, one yellow tile, is there any use to build soil enhancement? If the actual project is going to take up that square, then what is the point?
And, when I send a constructor to a starbase (mining), I can only install attack modules. No defense ones. I can install +10 beam, missile, and mass driver, but there are no choices for adding defense, which by the tech tree looks like they should come about at the same time. Is this a bug or am I missing something?
