Skin geometry cached

I use skin for NPC... Than I change geometry for that skin.
But always show old geometry... Why?

 

I ran into this issue as well. Seems like the client caches the geometry, no idea why :|
For now, I'm changing the geometry name everytime I update the geometry by concatenating random string to the name.

PHP:

public function createNewGeometry(string $geometry_name, string $geometry_data) : array{
    $random = uniqid();
    $geometry = json_decode($geometry_data, true);
    $geometry[$geometry_name . $random] = $geometry[$geometry_name];
    unset($geometry[$geometry_name]);

    return [$geometry_name . $random, $geometry];
}

[$new_geometry_name, $new_geometry_data] = $this->createNewGeometry($geometry_name, $geometry_data);

// use $new_geometry_name, $new_geometry_data


 

Thanks
