Co-op Hardcore Plugin

Plugin category: Utilities

Minecraft version: 1.15.2

Suggested name: Co-op Hardcore

What I want: The idea of this plugin is that when a player dies, it will kill all players on the server (best used with a group of 2 or 3), and set them into spectator (like normal hardcore). Then, have a command that can restart the server and regenerate the world without having to go into the file directory.

I know people have asked for this before, but it was most of the time declined for the "lag" that is caused by generating a new world, but the whole idea for this one is to simply have it restart the server as if you were doing it in singleplayer.

Ideas for commands: /resethardcore (Will delete the world and restart the server to regenerate it.)

Ideas for permissions: hardcore.reset (/resethardcore)

When I'd like it by: asap

Also another possible way to do it, is to simply teleport all players to say, a few million blocks out and set that as the new world spawn as well.

My plugin.
It does more stuff, but also should fulfill your needs (the page is in german, but you can change the language in the config.yml).
All players join a 'challenge' with /challenge join. For your needs, you open the GUI with /settings and select the first item (player head). When you die and are in spectator, you do /challenge reset and then restart the server.
Note: You need ProtocolLib to run this plugin.

World generation will always cause lag
