Config error

Hi!
1. I get set all right and it gives no error but when I run /stop and try to teleport to the world in the coords without set again simply returns "Internal Server"

 

config.yml

PHP:

---
Spawn:
  x: 255.700000
  "y": 70.000000
  z: 255.700000
  mundo: worldtw
  yy: 0
Spawn1:
  x: 256.566500
  "y": 66.000000
  z: 252.873400
Spawn2:
  x: 256.692000
  "y": 66.000000
  z: 258.605800

        $world = false;
        if($data['Spawn']){
            if(!$data['Spawn']['mundo']){
                return $this->getServer()->getDefaultLevel()->getName();
            }else{
                return $data['Spawn']['mundo'];
            }
        }else{
            return $data['Spawn']['mundo'];
        }
    }

    public function getWorld(){
        return $this->config->getAll()['Spawn']['mundo'];
    }

    public function getY(){
        $y = $this->config->getAll()['Spawn']['yy'];
        return $y;
    }

    public function getSSpawn($value = false){
        $data = $this->config->getAll()['Spawn'];

        $x = $data['x'];
        $y = $data['y'];
        $z = $data['z'];

        if($value){

            $mundo = $data['mundo'];

            $pos = new Position($x, $y, $z, $this->getServer()->getLevelByName($mundo));

            return $pos;
        }else{
            $pos = new Vector3($x, $y, $z);
            return $pos;
        }

hello?

 

cof

 

The error appears because the chunk of the specified coordinates are not loaded

 

how do I fix this?

 

PHP:

$server->loadLevel($level);
// OR BY NAME
$server->loadLevel($server->getLevelByName("Level's name"));
