savegame (all mods come from mod portal, but loading without mods shouldn't cause any issues)
On a related note, I'm wondering if the left input should simply be disabled for the basic oil processing recipe. That way, if you're upgrading to advanced processing later, you already have the correct input for crude oil (and you could even easily switch back and forth between basic and advanced, which isn't possible anymore now that the game prevents incompatible fluids mixing)
