I have an smp type server for me and my friends and Im using multiverse-core because I want to create another world for us to play on. I want to use multiverse core so I can go between world1 (world name of the first world) and world2 (world name of the new world) but then no one else can (I have operator status btw). World1 is the original world (I do not want to delete it) and world2 is the "reset" world. I want to make it so everyone stays in world2 and cannot go back to world1. I've tried many solutions, but everytime my friends die, they go back to their spawnpoint in world1 instead of spawning in world2. How can I make it so my friends cannot go back to world1 and stay in world2? Incase it might affect anything, the plugins I'm using are: Armorstand editor, bettersleeping3, discordsrv, essentials, fastleafdecay, multiverse-core, TAB(it's disabled), veinminer, and viaversion. My server is also in version 1.18.
