I was able to reproduce my issue on a freshly setup and up-to-date server with the latest version of Multiverse plugins with no other plugins and with no kinds of other server or client mods.
Description
Upon typing a Multiverse command a player can crash a server.
Steps to reproduce
Simply type /mv __REDACTED__
into chat.
Expected behavior
Does not crash the server.
Screenshots
SCREENSHOT REDACTED
I can confirm it too.
Adding a permission in plugin.yml for all commands has fixed the issue for me.
Crash is also possible in older versions. it works with all versions without permissions in plugin,yml
I can confirm this a bug. Someone did same thing to crash my server less than an hour ago on server version 1.13.2. Then went to my 1.16 server and did same thing. This exploit appears to exist in all version of multiverse going years back.
Update to latest dev builds, we will push a release asap
I created a plugin for those unable to or unwilling to install the latest version of Multiverse to prevent people from getting their servers crashed.
