With this mod, mining buildings will return the items required to craft it instead of the actual entity being mined. Works with expensive/normal mode, and (probably) all mods.
i love this mod. it's especially fun while living the lazy bastard life!
but it duplicates items.
all entities with a recipe yielding more than one product are affected.
this includes: transport belt, normal and fast underground belt, underground pipe, small electric pole, rail
