corrupted Minecraft world

Fixing corrupted chunks or whole worlds in Minecraft isn’t necessarily a hard thing to do. Those corruptions rarely occur on the vanilla version of the game, but mods tend to break the game from time to time.

If you’re on the receiving end of this, we are sure you fancy restoring the corrupted world instead of starting from scratch. There are multiple ways to fix corrupted Minecraft worlds and we provided you with the two below.

How do I fix corrupted Minecraft worlds?

  1. Create a new world and retrieve data
  2. Try with the Region Fixer

1. Create a new world

The first thing you can do if your Minecraft world gets corrupt is to create a new world and use some of the data files to retrieve as much of the old world as possible. Have in mind that this applies to the world only, as all your belongings and wear are not recoverable. What you’ll need to do is to back up the corrupted save file and use some of its data files to restore it into a new

Follow these steps to recover corrupted Minecraft world:

    1. In the Windows Search bar, copy-paste the following line and press Enter:
      • %appdata%.minecraftsaves
    2. For the remainder of the tutorial, we’ll call the corrupted world World C. Copy the World C folder, rename it to World C and save it in the Saves folder.
    3. Start Minecraft and re-create the corrupted world as a new world.  Name it Blank, save it, and close Minecraft.
    4. Go back to Saves folder (%appdata%.minecraftsaves) and you should see a newly-created Blank world.
    5. Copy the following files from the Blank folder to backed up World C:
      • level.dat
      • level.dat_mcr (not always present)
      • level.dat_old
      • session.lock
    6. Restart Minecraft and load World C.

2. Try with the Region Fixer

If you have an older backup of your world, you can use the Region Fixer to restore it or remove everything from your server locally. Corrupt worlds will cause your server to crash and that’s the last thing we want. What you need to do is download your backup and the server world. Now you can use an older backup to restore the world instead of starting from scratch.

Here’s how to use Region Fixer:

    1. From the in-game Multicraft Control Panel, choose File and then Backup. Save your world and exit the game.
    2. Download your Minecraft server world to your PC.
    3. Download Region Fixer from Gitbub, and extract it.
    4. Open Command Prompt in the extracted Region Fixer window (Shift + Right Click) and enter the following commands:
      • cd <full directory path>
      • egionfixer.exe -p 4 –delete-corrupted <full directory path to world folder>
    5. Don’t forget to replace full directory path with the path to extracted Region Fixer and full directory path to world folder with the path to the World folder.
    6. Upload your world again with an FTP tool and look for changes.

With that said, we can conclude this article. Don’t forget to share alternative solutions or questions in the comments section below. If you’re still stuck with an error, consider posting your inquiry in the official forum or contacting support.
