Worlds
The Worlds tab allows you to manage multiple Minecraft worlds on a single server.
You can switch between worlds, create new ones, import existing maps, or delete unused worlds.
This is useful for keeping separate survival, creative, event, or test worlds without creating multiple servers.
Important: Server Must Be Stopped
The server must be stopped before switching or modifying worlds.
This helps prevent corruption or incomplete saves.
Before making world changes:
- Stop the server
- Wait until fully offline
- Manage worlds
- Start the server again
Existing Worlds
Saved worlds appear as cards on the page.
Each world may display:
- World name
- Difficulty
- Seed
- Active status
Example:
- world
- four_villages
The currently loaded world is marked ACTIVE.
Seed Visibility
Seeds may be hidden by default.
Use the eye button to reveal the seed value.
Seeds are useful for:
- Recreating worlds
- Sharing terrain generation
- Finding structures with seed tools
Switch Worlds
Click Switch on a world to make it the active world.
After switching:
- Start the server
- Players will join the selected world
Only one world can be active at a time.
Delete a World
Click Delete to permanently remove a saved world.
Use caution:
Deleting a world removes builds, player progress, and terrain unless backups exist.
Always back up important worlds first.
Create New World
Use the Create New World section to generate a fresh map.
Typical fields:
World Name
Choose a folder/name for the world.
Examples:
- survival_main
- creative_build
- hardcore_run
Seed (Optional)
Enter a custom seed for specific terrain generation.
Leave blank for a random world.
Difficulty
Choose starting difficulty such as:
- Peaceful
- Easy
- Normal
- Hard
Then click Create World.
Import World (ZIP)
Use Import World (ZIP) to upload an existing Minecraft world.
Useful for:
- Moving from another host
- Restoring a backup
- Uploading custom adventure maps
- Bringing in a single-player world
Typical steps:
- Stop the server
- Click Choose File
- Select the ZIP file
- Click Import World
- Switch to the imported world if needed
- Start the server
Recommended World Uses

Troubleshooting
World not appearing
Check:
- ZIP imported successfully
- Correct folder structure inside ZIP
- Server was stopped during import
Wrong world loaded
Use Switch and confirm the desired world is active.
World missing progress
You may be on a different world than expected.
Check active world name.

Possible causes:

Tips
- Name worlds clearly.
- Keep backups before deleting or importing.
- Stop the server before all world changes.
- Use separate worlds instead of risky resets.
- Store old worlds for nostalgia or future events.
