With the Pick Up And Haul Mod, colonists will gather everything they can carry in their inventory, and haul it all to a stockpile.
This hauling mod will greatly increase hauling efficiency, because pawns can now carry more than one gun or t-shirt. These smart and intelligent colonists can now use their inventory! You gotta see it to believe it.
The Pick Up And Haul Mod should work fine with other hauling mods like AllowTool’s Haul Urgently, Please Haul Perishables and Stack Merger, but they don’t gain the inventory-benefit.
If you want to remove this mod from your game, draft everybody before doing it.
