when sorting items in the alloysmelter with a capacitor and an ItemStack with multiple items, the first alloy material is storted back into the first alloy smelter slot, but the capacitor isn't put back into the capacitor slot, as only later slots are checked for sorting back and the other slots don't accept capacitors
