String Duper Restorer Mod brings back a popular game mechanic for newer updates. It removes the recent patches that stopped string duplication machines from working, so you can build your infinite string farms again. The mod lets you keep your old redstone designs running without worrying about the new restrictions.

Features:
- Brings Back Duplication: Reverses the specific game patches (MC-129055 and MC-59471) that broke string duplication.
- Lets you build and run classic string duper machines on newer game versions.
- Helps you gather endless string for crafting bows, fishing rods, scaffolding, and wool.
- Saves you time from hunting spiders or looting mineshafts just to find string.
How to Use:
- Build your standard string duplication machine in your world.
- Adjust your redstone timing if your machine stops working, because recent game updates changed how redstone signals travel.
- Turn on the machine to start collecting endless string.
