Description
I want to permanently delete a world with /mv delete command but after restart the server the world is back again.

Steps to reproduce
I want to permanently delete 2 of my worlds: buildbatttle7 and spleefarena.
I run /mv delete buildbatttle7 and /mv confirm.
Then I do the same thing for spleefarena.
If I check with FTP I see the the world's folders has been deleted.
Then I restart the server.
After restarting, the worlds that I removed are still there and the world's folder has been atumatic recreated.

Expected behavior
World should be permanently deleted.

Screenshots
I think it is not relevant.

Closing as can't reproduce and no further response from the author. Feel free to open a new issue if needed.

I can't reproduce with the latest release, the only thing I can say is it may be due to a test build of 5.0.0 in which I don't have time to work on atm.

Do you suggest me to move back on latest release or wait for next 5.0.0 update?
(if move back, do I need to reconfigure or can I use same yml files?)

Yes, I suggest testing with the release version.

if the world folder has already been removed, you can use /mv remove worldname

When I use /mv delete the folder has been deleted BUT when I restart the server the folder has been recreated.

I can't reproduce with the latest release, the only thing I can say is it may be due to a test build of 5.0.0 in which I don't have time to work on atm.
