[PROBLEM] Environment variables and php artisan

I recently started using laravel homestead (2.0) for my development environment, but i encountered a problem. In my homestead.yaml file i setted my environment variables like so:

variables:
    - key: APP_ENV
      value: local

and in my bootstrap/start.php i do:

$env = $app->detectEnvironment(function(){

    return getenv('APP_ENV');

});

And this works fine in the browser. When i var_dump(getenv('APP_ENV')) i get local as response. However, when i do php artisan env, i get the following:

Current application environment: 

I also got my database variables like host and usernames as environment variables, but those arent set in php artisan neither. I've searched a while now and havent found any answer. Homestead should provision those variables, but it only does a small job of doing so. Am i doing something wrong? Please help because im kinda stuck atm...
