I tested with expensive recipes (marathon preset):

The recipe for electric-mining-drill and for submachine-gun are the same as the original recipes. There should be the burner-mining-drill or the pistol included.
I guess it is correct when you play with normal recipes, but the expensive settings might be wrong.

No, it's incorrect with normal recipes as well.

I looked at the lua files for the mod, and everything appears to be correct for what he's trying to do. Notsure where he'll find the fix.

Also experiencing this, as well as missing a lot of recipes, like the ore crusher upgrade and the steel chest upgrade, even though I can craft the items and have the research unlocked. I can even see the recipe that's supposed to be there in the research screen but it's not in the crafting window.

Will look into this.

They seem to be showing up.
