Preventing Schematicannon Item Duplication on a Server

If you host a multiplayer world with the Create mod, players might attempt to use the Schematicannon to duplicate special items and blocks without paying their proper resource costs. Create Dupe Patch Mod resolves this issue directly on the server level.

Server-Side Setup

Because this fix operates strictly as a server-side mod, regular players joining the world do not need to install it on their own game clients.

1. Place the mod into your server's mod directory.

2. Start or restart your server.

3. Allow players to connect normally using their standard client installations.

Verifying Exploit Prevention

Once the patch is active on the server, the item copying glitch is closed. When players place a Schematicannon and load schematics, the cannon is forced to evaluate and demand the true material costs for all placed blocks. Any attempts to generate special items or blocks carrying hidden data for free will fail, as the machine will actively refuse to place blocks unless the genuine, exact items are provided in adjacent storage.
