Supply ships were removed to simplify game, as some players found them confusing, and AI would be confused by them.hey, how I can build supply ship for lunar cities? can't find them anywhere. half of nanotech era now, I already played several games in space maps and supply ships were always becoming acceessible in similar time like construction ships or settlers, but I don't remember when exactly
Those buildings, that formerly could be built with supply ships are now buildable for cheap on Moon.
Similarly all buildings buildable by space rewards are now buildable directly too.
Space mission units stayed, since they can bring raw commerce too.
