Supply Lines Mod extends MineColonies and Create by connecting colony item requests directly to factory production lines. Colonists ask for tools, food, and building blocks just like they always do, but this mod lets automated machines fulfill those orders instead of manual player hauling. A dedicated worker accepts goods from belts, depots, and logistics networks so settlements run alongside large industrial setups.
