The worlds are still listed in the multiverse config.

As I wrote above, remove them from the config.

before, I delete the folder with config and worlds. After that i delete the worlds. After, i installed the multiverse-core againe, and config regened this worlds, and worlds are regened in the world tab

I did it when server was offline

Did you do this while the server was online? Make sure that your server is offline while doing that.

Thank you for help, I try to do it later and say you if it working

I successfully deleted the world MoodCraft with the command mv delete MoodCraft in the console

Edit:

I found the problem. PlotSquared is always regenerating the world.

Make sure to remove the world also from the plotsquared config.

What I did:

"mv delete MoodCraft " in console

"mv confirm" in console

Removed MoodCraft from PlotSquared config

restarted server

It is working! Thank you for help!
