So I had a hybrid freighter/colony ship load colonists and infrastructure at Earth then unload them to Luna, then repeat for Mars, which resulted in each body having 2 colonies, 1 with infrastructure and the other with colonists. Couldn't figure out how to merge them so I deleted the colonists to avoid wasting the infrastructure minerals. Is there no way to merge or was I missing the button? Is it an intended feature for 7. 2/8?
