Hi I have a problem. It's late in thegame. I'm on the campaign with the mission where you have to convince the Torians to join you against the Drengen.

Anyhow, my shipyards all say "never" for all the ships I want to build on all my colonies. Why is that? How can I fix it? My economy is fine I'm earning about 600 a week.

Edit: And the shipyards aren't full.
