This is a hotfix for players to have the ability to successfully remove Metal and Stars from an existing playthrough without breaking the save. This tweak adds back the missing item-subgroups "ringworld-processes" (Gold Cable & Gold Ore) and "mirandus-processes" (Neodymium Rails) and simply re-maps them to the "intermediate-products" group so that the server doesn't throw an "item-subgroup does not exist" error and refuse to start.
