Uhm.. That thing should have been removed I guess.. We make use of the vanilla smelting list. I don't think the smelter uses the stuff registered in that way. (im not 100% sure though)

Indeed, make sure you add the recipe to the vanilla furnace. the smeltery will then pickup the recipe. Took me 2 days to figure this one out.

Closing, functionality will be restored.
