DEUF 9minecraft Mod fixes broken entity identifiers when loading Minecraft worlds. Copied saves, restored backups, and edited world files can cause duplicate ID errors that spam server logs or stop a world from loading. This mod catches matching IDs right away and gives new entities a fresh identifier. Both mobs stay safe in your world, and your save loads without errors.

Features:

Automatically detects duplicate entity identifiers before they cause save errors.
Assigns a brand new unique ID to duplicate mobs, items, and vehicles.
Prevents server console spam from repeated duplicate ID warnings.
Keeps both entities in your world instead of rejecting or deleting one.
Runs quietly in the background without adding extra items, blocks, or menus.
Offers an optional config setting to log each repaired entity in the console.
