Describe your suggestion

Currently the Crushing Wheel and Millstone from Create specifically require vanilla cobblestone when making gravel.

I suggest allowing any forge:cobblestone to be used in the recipe instead, like has been done already for the Immersive Engineering Crusher, the Mekanism Crusher and the Thermal Series Pulverizer.

Why would you like this added/changed?

I am currently in need of sand, and because I have a ton of cobblestone I figured I'd go the cobblestone -> gravel -> sand route. However, due to world gen, most of my cobblestone is various versions like Limestone and Gabbro, which doesn't turn to gravel without getting into FE generating mods.

Can take another look, but I recall this breaking something... Some of the other stones are used to generate other resources in the create crusher I think.

Yeah, this ends up breaking a few fun recipes that I think are better to keep than to lose in this sort of standardization. Granite to Red Sand, for instance.
