KeepHeld restores each Pokémon's held item after a Cobblemon battle (victory, capture, or flee). Oran berry, Focus Sash, Knock Off, Trick: the item you had at send-out comes back.
Requires Minecraft 1.21.1, NeoForge 21.1.x, Cobblemon 1.7.3. Put the jar in the server mods folder. Clients do not need it.
Inspired by the Fabric Held Item Saver idea. Original MIT code, not a port.
