I am just in the beginning of a new game and there are 4-5 civilian cargo only.
There were about 500 LG infrastructure on the moon, I set up a contract to move them back to Earth and they did it, except for last 2.8, so they have the capacity to do it. Can the reason be because in the meanwhile I started to colonize Mars, so they are now busy moving infrastructures there and on the Moon, delaying the civilian contract? They were also able to move 5 terraformers units from Earth to Moon, but still these 2.8 not.
