Just as the title says, if I try to craft the Iron sheet metal blocks I get 16 empty cells from Nuclear Craft instead of the 4 sheet metal blocks. This is part of a quest and also part of some of the machines like the assembler and the tanks. I am using the Iron plate from Immersive engineering, not the other plates from other mods.
frog try using a normal crafting table there should be a arrow in the GUI of the vanilla crafting table that will change between recipes
