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.
So, this is a bit of a hedge dream of mine and your mod fits part of it perfectly. Thank you.
I was curious if doing the opposite is possible. So, say you have all the resources (or after you craft all of the resources) required to build something, you can just build it from the resources rather than need to craft it first.
