Playing on a multiplayer server, version 1.2.21.

Im stuch in chapter 5 because the NuclearCraft Basic Plating recipe doesn't work.

Recipe in JEI says:
lead ingot/grapite dust
graphite dust/cadmium ingot

saw the recipe was suppoe to be tweaked in 1.2.20, maybe the server files didnt have the recipe updated?

That is the tweaked recipe. It uses 1 cadmium ingot & 1 lead ingot instead of 2 lead ingots

Please better explain your issue. What doesn't work exactly? What happens when you try to craft? Does it fail to show any output in the crafting grid? Perhaps could you include screenshots?

Are you playing on the official server? On your own server? on somebody else's? It could be an error on the side of the server owner not updating the scripts. I opened up the server zip that was uploaded and it seems to include the appropriate recipe.

Also, the stack of diamonds thing is a bug specifically with the tinkers table.

Contacted the server admin. It seems to be an issue in his end. Thanks for the help
