When I silk touch stone, the item I get from it will not stack with stone from a furnace. This creates another problem with the Stone Mason, I have to silk touch my stone if i wish to trade it. Both stones behave the same with crafting and smelting, the 'false' stone just cannot be traded or stacked with silked stone

This is because of MCPE-47907. Cobblestone smelted in a furnace gets a insanely high damage value. Honestly I would consider this a duplicate of MCPE-47907. Because of that I would type the extra info on that ticket to be safe. Have a great day! 🙂
