Blocks every method of duplicating maps: cartography table, crafting table, 2x2 grid, and the Crafter block. Official build for Purpur 1.21.11.
⬇ Download on ModrinthFeatures
- Blocks map duplication in the Cartography Table
- Blocks map duplication in the 3x3 Crafting Table
- Blocks map duplication in the 2x2 inventory crafting grid
- Blocks automatic map duplication via the Crafter block (redstone auto-crafting, 1.21+), detected at runtime so the plugin stays stable on versions without it
- Detection is based on the actual ingredients present (a filled map plus an empty map), not on internal recipe keys — reliable across different server builds
- Sends a clear action bar message ("Non puoi craftare questo.") when a duplication attempt is blocked
