i cant solve it yet but i sm really exited that i can read it cuz im learning coding :3

Solved, thanks

The reason why is you only use onCommand once, and add multiple commands to it

For example

public boolean onCommand(CommandSender sender, blah blah blah) {
if (sender instanceof player) {
if(cmd.getName().equalsIgnoreCase("hhub")){
//DO YOUR STUFF HERE
} else if (cmd.getName().equalsIgnoreCase("hserver") {
//DO NEXT COMMAND HERE
}
}
}

Hope I helped
