First of all Im new to these forums so wasnt sure which section to post this in, if its the incorrect one then my apologies. I am trying to make an Industrial Grinder on our FTB server and I am having problems with the recipe. The precise parts Im having trouble with are the 3 Diamond Grinders, when I put the recipe materials in nothing happens, which are diamond dust, steel ingots and a diamond. The recipe that is shown lists an Industrial diamond, Im wondering if this may be the problem. Since a week or so ago the Industrial diamond seems to have been automatically replaced with normal diamonds in game when I produce them. There is an alternative mat, the wolframium grinder which is pretty expensive for me to upgrade my furnace to make so I wanted to ask you guys if the first recipe with diamond grinders is currently not working. Thanks for any help you may be able to offer.
