Ah! The Mass Drivers on the planets of Proxima A are sending a nice steady stream of mineral packets to the colony on the moon of planet 4 of
Proxima C. Steve, I don't know how you did it, but I tip my hat to your programming skills.
Just need more automated mines on the 3 planets
of Proxima A, and setup mines on the others, to increase the mineral flow. Strangely, Proxima C is the only one of the three stars in this trinary
system that has developed habitable, or terraformable, worlds. ^_-
