Multi log tree farm

A multi log tree farm by Shulkercraft, designed by occultgentmc, and one of the largest builds in the library at 73 sticky pistons. Trees are grown from a dispenser of bone meal and blown apart by duplicated TNT, with pistons pushing the logs to hoppers and twelve chests. It runs birch, oak or spruce from the same build, and the one thing it depends on is TNT duplication, so the farm dies with that bug and needs server config changes to run on Paper.

• Do not right click the redstone dust while placing the sapling. It turns from a cross into a dot and the pistons stop pushing. This is the most common failure by a wide margin, and the fix is to pick the dust up and place it again.
• On Paper or Bukkit servers set allow-headless-pistons to true or the TNT will not duplicate at all. Test it by placing sand and breaking the block underneath, and a crash means it will work.
• If spruce saplings will not grow, start the farm on oak and then switch to spruce in your hotbar without stopping it.
• Water leaks and destroys a redstone dust and torch. Adding a block in front of the temporary block at 1:56 prevents it.
• Check that 12:40 is a slab and not a full block, and that the redstone at 13:40 goes back after the temporary block comes out. Both are easy to miss and both stop the pushing.
• With spruce the leaves crush and fling saplings out of the farm entirely. Wall the sides around the pistons to keep them in.
