I spent 15 minutes trying to figure out why my newly researched construction nanites weren't building a medium dome that I had intentionally put out of range of my drone hubs to see how the tech works. Then it dawned on me... there was a tiny little rock in the middle of the construction site that needed to be cleared before the site could officially progress to construction. It seems odd that construction nanites can carry concrete and metal, but they can't clear the ground for the construction to begin. Please give them this power so the nanites can truly shine and turn Mars into a bustling metropolis!
