What it does

Players reproduced the duplication problem with the mod removed, and it did not depend on Aeronautics DupeFix being present. Once this mod is installed alongside Create, Create Aeronautics and Sable, the duplication no longer occurs. The mod is server-side only, so players join without installing it, and it is published for NeoForge on 1.21.1 only, with version 1.3.0 dated 2026-07-28. It is open source under the MIT License.
