Server Version

The command did not work

paper-1.21.4-212.jar

Bug Description

The expected behavior would be the world gets deleted and reset with a new seed, while keeping the gamerules of the existing world.

Actual behavior: Nothing happens, exception occurs.

Steps to reproduce

/mv regen pocket1_nether -s --keep-gamerules

results in that exception being thrown.

I can verify that I am not able to see that game rule with the game rule command, either.

I've seem reports that "experimental" has to be enabled.. not sure.

Agreements

• I have searched for and ensured there isn't already an open or resolved issue(s) regarding this.
• 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.

Found this:
#2822

Was hoping the worldBorder would also get remembered. Looks Like I will do it manually! Thanks

This has been fixed in mv5, you can either get the build from our discord or the artifact attached in #2824. per world WorldBorder command will be added in mv5 sometime in the future. You can stay updated of the development in our discord.
