 017-axe=(Default enabled) IMPORTANT NOTE: It is highly recomended that infinite durability is enabled when using this option to prevent duplicate items. Implements the FFF-266 changes as best as possible. Instead of mining-tools being crafted, they are inserted and locked to the player's tool slot when they're researched. The best mining-tool is used over lower speed ones.
 017-equipment=(Default enabled) Adds belt-immunity-equipment tech and recipe (FFF-256). Note that if another mod that adds belt-immunity-equipment recipe is present, this mod's unlock will be disabled. Disabling this option in an existing game will NOT remove the item - only the recipe & tech.
