Why is it not changing?

Hi
I need Help because plugin don't change the number of current

PHP:

$this->arena = new Config($this->getDataFolder() . "/arenas/" . $levelname . ".yml", Config::YAML);

PHP:

if($this->arena->get("buildtime")==0)
                    {
                        $this->arena->set("current", $this->arena->get("current") + 1);

 

You must save.

PHP:

// +1
$this->arena->save();

 

Use this.

$arena = $this->arena;
$arena->set();
$arena->save();

 

I have this
