So, I recently installed this a few days ago and have been playing around with this modpack, however when finally getting around to setting up ore crushing and refinement, it seems that while "Bobmonium" is called to be crushed into materials, the blast furnace is asking for a "Pyanodons Raw Ores" Tin ore. It also appears to be a similar situation when feeding lead ore into a blast furnace.

So. Is there any way to fix this? Im not really familiar with mods or how they work, but id be appreciative if this could be resolved without neccessarily starting over from scratch.

In 0.18.15 there is no such problem, the correct ores are refined. In your case there might be a problem with "PyCoal Touched By an Angel", check that it is installed correctly.
