Even though tin ore from one mod has a working fractured version with recipes, the tin ore from Mekanism creates a whole different fractured ore instead of the existing one and the new fractured tin has no recipes, so it cant be smelted.

Nickel from electricraft, osmium from mekanism don't have recipes.

Doesn't seem to have a item name to fix with minetweaker.

Thanks.

Everything has an item name. Hold the item in your hand and use /mt hand
