How to install a worldgen pack to my server? / The world on my server didn't change after installing the packs / New biomes only generate in unexplored chunks
OR OR
 * Cause :
 * You tried to install a worldgen datapack on an already generated world.
 * You tried to install a worldgen datapack on an already generated world.
 * Your server loaded the world without a player joining and without taking into account new custom biomes, even after a world reset.
 * Fix :
 * Make a backup of your server, create a singleplayer world with Terralith(Vanilla OR Fabric)/Incendium(Vanilla,Paper OR Fabric)/Nullscape(Vanilla OR Fabric) and any other datapacks you are using. Make sure you add the datapacks using the datapack button. DO NOT add them AFTER you create the world. As soon as you load the overworld, leave the game. On your server, make a backup, then delete the world, the_nether, and the_end folders. Find the folder of the entire singleplayer world (it is the folder that contains region folder). Rename that folder to world, and move it to your server. Start up your server.
