Great point, that aspect slipped my mind. For now I will revert this hand craft change.
I'm still debating hand crafting. The pattern with other ores is they must be processed in a machine(smelter) before they are usable. Changing one ore to another doesn't seem like something that should be possible to do in hand. Also, having these recipes as hand craftable allows morphite to show in the 'total raw' section of recipes, and I don't find that helpful.
On the flip side, this mod has its roots in being simple, adding a minimal amount of complexity so the player can have essentially a wild card raw resource. Having it hand craftable is more forgiving than requiring a machine.
Since now there aren't any hard bugs having it hand craftable, I'll leave it in for now.
If you are curious as to what sparked my interest into all of this:
