- Hold the item and use it (right-click / tap) to open the fixer menu.
- Select Scan & Repair to lock onto nearby NPCs and begin the repair sequence.
- Watch the action bar for live progress — stay near your targets until repairs finish.
- Collect your emerald and XP rewards when the session completes successfully.
Overview
NPC Chunk Fixer is a utility mod that gives you a single craftable tool to stabilize villagers, wandering traders, and other NPCs that have lost their normal chunk-related behavior. When something feels off with a nearby NPC — they're stuck, unresponsive, or behaving strangely — you pull out this tool, scan the area, and let a timed repair sequence sort them out.
What It Adds
| Item | Description |
|---|
| NPC Chunk Fixer | A handheld utility tool that scans nearby NPCs and runs a timed repair sequence on them. Stacks to 1. |
The mod also adds a scoreboard objective called NPC Fixes that tracks repair activity across all players on the world.
How To Use
Opening the Menu
Use the NPC Chunk Fixer while holding it to open the NPC Chunk Fixer menu. The menu shows your lifetime stats and gives you two options:
- Scan & Repair — Finds loaded NPCs within 48 blocks and starts a repair session.
- Stats — Opens a stats screen showing your lifetime fixed count and successful run count. From the stats screen you can also launch a new repair session.
If a session is already running when you use the item, the action bar updates with current progress instead of reopening the menu.
The Repair Session
Once you start a session:
- Up to 12 NPCs are locked in as targets for that run.
- A 18-second countdown begins, with the action bar displaying live progress in the format
NPC Chunk Fixer: X/Y fixed - Zs.
- The tool repairs one target approximately every 2 seconds.
- Stay near your targets — moving too far away from where you started the scan can cause the session to lose track of entities.
Session Outcomes
| Result | Condition | Reward |
|---|
| Success | All locked targets are repaired before time runs out | Emeralds + XP; lifetime counters increment |
| Failure | Timer reaches 0 before all targets are fixed | On-screen message showing how many were fixed; no reward |
If no NPCs are found within range when you scan, you receive a message and no session starts.
Crafting And Obtaining
The NPC Chunk Fixer is crafted at a standard crafting table. The recipe unlocks automatically once you have a compass, emerald, or redstone in your inventory.
The item does not stack, so you only ever need one. It has a short cooldown between uses.
Abilities And Mechanics
- Scan radius: 48 blocks around you when the session starts.
- Max targets per run: 12 NPCs.
- Session duration: 18 seconds total.
- Repair pulse: One NPC is processed every 2 seconds.
- Supported entity types: Villagers, V2 villagers, wandering traders, and NPCs.
Progression And Strategy
- Your lifetime fixed count and successful run count are saved permanently per player and reflected on the NPC Fixes scoreboard, making them visible to the whole server.
- To maximize a session, position yourself in the center of a village or trading post before using the item — this ensures the most NPCs fall within the 48-block scan radius.
- Since only 12 targets are processed per run, prioritize areas with the highest density of troubled NPCs.
- Successful runs reward emeralds and XP, making regular use of the tool genuinely profitable in survival play.
