The stone glitch does not work. It's just visual. If you try to use the stone it won't let you. Farmed 50 stone did the glitch to get 150 stone and tried to craft 3 furnaces and the game won't let me. When you log off and come back on the duped stone disappears.
Yeah it's just visual. I did the dupe with 50 stone. Did the glitch got 150 stone. Tried to craft 3 furnaces and it would only let me craft 1 even though it said I had 150 stone. It stays in your inventory when you open and close it. When you disconnect and log back on it disappears from your inventory. It would be crazy if it actually worked though lol.
