Copper spleaves blocks are an unsupported item due to being an April Fools' joke, and therefore such issues relating to them will not be fixed.


  • Copper spleaves is a reference to the Minecraft minigame spleef. Spleef is a competitive minigame played within Minecraft. When playing spleef, players destroy blocks below other players, allowing them to fall off the playing field and into a pit. The object of the game is to be the last player on the field. Because of this, the name of the Copper Spleaves is a combination of the words "Spleef" and "Leaves".
