Follow this format: groups: default: worlds: - world - world_nether - world_the_end default-gamemode: SURVIVAL creative: worlds: - creative default-gamemode: CREATIVE # 'default' and 'creative' are the names of the groups worlds: is a list of all worlds in the group If you have 'manage-gamemodes' set to true in the main config, the server will use the 'default-gamemode' here to know what gamemode to put users in. groups: default: worlds: WG1 WG1_nether WG1_end default-gamemode: SURVIVAL Kalechips: worlds: KaleChips KaleChips_nether KaleChips_the_end default-gamemode: SURVIVAL Survive: worlds: Survive Survive_nether Survive_end default-gamemode: SURVIVAL  So I have a nether and end for each world, but it gives me different inventories for each even though I have them in groups
