If I type "/help", then I see "LuckyBlock: All commands for LuckyBlock". So I type "/help LuckyBlock" and it gives only one command option "/addworld:". But I don't know how to use this command. Only have the one world on my server using Spigot... so is the world named "default"? Tried "/addworld:default" but that didn't work. I'm clueless.
