I thought that since you can craft all stone tools, ovens, brewing stands and other stuff recuiring cobblestone from cobbled deepslate, cobbled deepslate would work in all crafting recipes as replacable for cobblestone but when i tried to make any redstone machine that recuired cobblestone and I tried using cobbled deepslate it wouldnt work. Im not sure if thats how its supposed to be but it doesnt make sense to me.
