I am unable to smelt stone ina furnace in my survival world.I tried making a copy and it still won't smelt but when I created a new world I was able to smelt stone but still cant smelt stone in my main survival world. Tried smelting cobblestone into stone than smelting it and once I smelting the 1 cobblestone into stone It combined into one of my stacks of stone but made it so the stack of stone it combined with was at 10 stone and could not be combined with any other stone blocks. It then let me smelt the 10 stone that was combined with the original 1 cobblestone that was smelted into stone then combined but all the stone i have silk touched will not smelt
