👻 FantasticGhostBlockRemover - Sorry & 1.0.17 Hotfix Update

FantasticGhostBlockRemover is a small but very useful server-side maintenance tool for Hytale servers.

First of all: sorry for the rough update path. Hytale 0.5.6 changed several internal API and command systems, and the automatic ghost block removal needed multiple fixes before it worked properly again.

With version 1.0.17, the automatic cleanup system should now work correctly again.

The mod can detect, list, manually remove and automatically clean up ghost blocks in loaded world areas.

This mod is especially useful after Hytale updates, removed mods, changed block IDs, broken custom blocks or world generation issues where old blocks no longer exist correctly on the server.

🆕 Update 1.0.17 - Auto Cleanup Hotfix

Version 1.0.17 fixes the automatic ghost block cleanup system for Hytale 0.5.6.

The mod now uses a safer queue-based system for automatic checking, but when AutoRemove is enabled, detected ghost blocks are removed automatically again.

This means admins no longer have to manually run:

/fgbr remove all

every time ghost blocks are detected.

⚠️ Important Config Notice

If you updated from an older version, please check your config file.

The most important setting is:

"ReplacementBlock": "Empty"

Do not use:

"hytale:air"

For Hytale ghost block cleanup, Empty is the correct replacement value.

If your config was created by an older broken version, either delete the old config and let the mod create a new one, or manually update it.

Config file:

fantastic-ghost-block-remover.json

✅ Recommended Config for Live Servers

{
  "Enabled": true,
  "RemoveReplacementBlock": "Empty",
  "Scan": {
    "ManualRadiusChunks": 5,
    "MinY": 0,
    "MaxYExclusive": 256
  },
  "AutoCheck": {
    "Enabled": true,
    "InitialRadiusChunks": 4,
    "QueueMaxChunks": 512,
    "WorkerIntervalMillis": 2000,
    "ChunksPerRun": 2
  },
  "AutoRemove": {
    "Enabled": true,
    "Mode": "safe",
    "MaxBlocksPerScan": 10,
    "RequireDoubleCheck": false,
    "NotifyConsole": true,
    "ReplacementBlock": "Empty"
  }
}

Important values

"AutoCheck": {
  "Enabled": true
}

Enables automatic scanning of loaded chunks.

"AutoRemove": {
  "Enabled": true
}

Enables automatic removal of detected ghost blocks.

"ReplacementBlock": "Empty"

This is required for properly clearing broken ghost blocks.

"RequireDoubleCheck": false

Recommended for automatic cleanup. Older versions could detect ghost blocks but only remove them after a manual remove command when double-check was enabled.

🧹 What are Ghost Blocks?

Ghost blocks are blocks that still exist in the world data but are no longer valid on the server.

This can happen when:

• A mod was removed
• A block ID changed after an update
• A world was generated with an older mod version
• Hytale changed internal block handling
• A custom block no longer exists
• A chunk loaded with outdated or broken block data

These blocks can sometimes appear as pink/black blocks, broken blocks, invisible blocks, invalid blocks or cause issues when loading areas.

🤖 How Automatic Cleanup Works

The automatic cleanup system only works in loaded chunks.

It does not scan your entire world at once.

When a chunk is loaded, the mod queues it for a background scan. The worker then checks a small number of chunks per interval and removes detected ghost blocks if AutoRemove is enabled.

Default recommended timing:

"WorkerIntervalMillis": 2000,
"ChunksPerRun": 2,
"MaxBlocksPerScan": 10

This means:

Every 2 seconds, the worker processes up to 2 queued chunks.
Up to 10 ghost blocks can be removed per scan.

This is slower than a full-world scan, but much safer for live servers.

---

🧭 Scan Range

By default, the manual scan checks a radius around the player.

Example:

5 chunks radius = 11 x 11 chunks = 121 chunks

This means the mod scans a large area around you, but not the entire world at once.

The automatic system also works only in loaded areas and does not scan your entire world instantly.

---

🔐 Permissions

Recommended LuckPerms permissions:

ghostblockremover.command.use
ghostblockremover.command.admin

Example:

/lp group admin permission set ghostblockremover.command.use true
/lp group admin permission set ghostblockremover.command.admin true

---

📁 Config

The config file is created automatically:

fantastic-ghost-block-remover.json

If you have problems after updating, please delete the old config once and let the mod generate a fresh one.

Then make sure these values are enabled:

"AutoCheck": {
  "Enabled": true
},
"AutoRemove": {
  "Enabled": true,
  "ReplacementBlock": "Empty"
}

---

⚠️ Important Notes

This mod does not scan your entire world instantly.

It only scans loaded areas to keep the server safe and stable.

For manual cleanup, use:

/fgbr scan
/fgbr list
/fgbr remove all

For automatic cleanup, make sure this is enabled:

/fgbr autocheck true

And check your config:

"AutoCheck": {
  "Enabled": true
},
"AutoRemove": {
  "Enabled": true,
  "ReplacementBlock": "Empty"
}

Always test the mod on a backup or test server before using it on your main world.
