⚙️ Limit Extender 15.20 — The Ultimate Repair Engine

English

Limit Extender is a high‑precision repair engine for Minecraft 1.20.1. It operates deep inside the game’s data systems, detecting corruption before it spreads and restoring broken structures instantly — all without touching gameplay.

If your world has corrupted chunks, invalid NBT, broken datapacks, or recipes that crash the game, Limit Extender fixes it silently and automatically. It’s the kind of mod you install once… and then wonder how you ever played without it.

🔧 Core Modules

  • NBT Fixers — Repairs malformed or corrupted NBT tags in entities, blocks, and player data.

  • Shadow Block System — Rebuilds invalid block states and prevents chunk‑level corruption.

  • Chunk Repair Engine — Scans, detects, and restores damaged chunks on the fly.

  • Datapack Repair — Fixes broken datapacks, invalid JSON, and missing structures.

  • WorldBorder Fix — Corrects misconfigured borders and out‑of‑range chunk generation.

  • Recipe Repair — Restores overwritten or invalid crafting recipes.

🚀 Why You Need It

  • Stops corruption before it becomes permanent.

  • Stabilizes long‑term worlds and large modpacks.

  • Essential for servers that can’t afford downtime.

  • Zero gameplay changes — pure backend protection.

  • Lightweight, fast, and fully compatible with Forge 47.x.

🛠️ Version 15.20

A more aggressive detection system, deeper repair logic, and optimized routines for massive worlds.
