I just built my first orbital terraformer using a base style ship with an orbital habitat. I have two of these vessels with one sitting above mars to aid the terraforming, the other I sent to a neighbouring system to begin terraforming a planet on it's own. I noticed that you can set a primary order as "terraform colony" so selected this for the second vessel to see how it functioned. After a time increment I say the second vessel had changed the orders I gave manually to head back to sol with a target in mind (not listed by name).
Does this order type turn the vessel into an auto terraformer? If that is so how do I outline how I want such vessels to perform and how can I prioritise planet terraforming and such?
