Sometimes you want a clean slate: a brand new world, or the same world regenerated from a different seed. This guide walks through both. It leaves your plugins and configs intact and only replaces the world itself.
Important: this permanently deletes your current world
Deleting the world folders removes everything built in that world for good. There is no undo. If there is anything you want to keep, back it up first.
- Stop the server from the Console tab.
- Open the Backups tab in the panel and create a backup, or download the world folder from the Files tab to your own computer. The Backups tab shows how many backup slots your server has.
Only move on once you are sure you have a copy, or you are certain you do not want the old world.
Reset the world
- Stop the server from the Console tab if it is still running.
- In the Files tab, delete these three folders: world, worldnether and worldtheend`. Together they hold the overworld, the Nether and the End. Deleting all three gives you a fully fresh world.
- Open server.properties in the Files tab.
- Find the level-seed= line. Leave it blank for a random new world, or type a seed after the equals sign to generate a specific world, for example level-seed=12345.
- Save server.properties.
- Start the server from the Console tab. It generates the new world on startup, which takes a little longer than a normal start.
That is it. When players reconnect using the same IP and port from the panel, they spawn into the new world.
What stays untouched
This process only replaces the world. Your installed plugins, their config files, your server.properties settings, whitelist and ops all stay exactly as they were. You are swapping the map, not resetting the whole server.
Troubleshooting
The old world came back after restart. The folders were probably not fully deleted, or the server was still running when you deleted them. Stop the server, confirm all three folders are gone in the Files tab, then start again.
I set a seed but got a different world. Check for typos and stray spaces in the level-seed= line, and make sure you deleted the old world folders. If the old world files still exist, the server keeps using them and ignores the seed.
Custom world generation from a plugin is not using my seed. Some world-generation plugins manage the seed themselves. Check that plugin's own config in the Files tab.
