what recipe are you using?
you still use the rolling machine iirc, but instead of the iridium ingots you have 'normal' iridum plates (made in the plate bender)....and instead of the diamond dust, i think you now use an industrial diamond. see if that works.
The RC Recipe for MMingots was removed and replaced with the plate one, and IAI are crafted with 4 Iridium plates, 4 Advanced alloy and 1 INDUSTRIAL diamond, you have the recipe correct? If not, check your config again, you may of disabled it.
That did the trick, thanks!
