SpriteKit SKCropNode Masks everything

I am trying to mask a node with SKCropNode class. I am doing it with my own init method in SKCropNode inherited class: 

- (id)init {
    self = [super init];

    if (self) {
        self.maskNode = [[SKSpriteNode alloc] initWithColor:[SKColor blackColor] size:(CGSize){50,50}];
        SKSpriteNode *contentNode = [[SKSpriteNode alloc] initWithImageNamed:@"Spaceship"];
        [self addChild: contentNode];

        self.userInteractionEnabled = YES;
    }
    return self;
}

It works as expected: Rectangle Mask

Now, I want to add background to the scene and a cropped spaceship with following code:

-(void)didMoveToView:(SKView *)view {
    /* Setup your scene here */

    //
    //background
    //
    SKSpriteNode * background = [SKSpriteNode spriteNodeWithImageNamed:@"background_game"];
    background.position = CGPointMake(CGRectGetMidX(view.frame), CGRectGetMidY(view.frame) - CGRectGetMinY(view.frame));

    [self addChild:background];

    TurretCropNode * cropNode = [[TurretCropNode alloc] init];
    cropNode.position = (CGPoint){view.frame.size.width/2,view.frame.size.height/2};
    [self addChild:cropNode];
}

I have just added few lines with adding background at the beginning (cropped node lines remain the same)

Here what I got now: Background + mask

Is it an expected behavior? Why cropped spaceship disappeared?

I am guessing that the image as shown below is your designated background. Have you checked your nodes zPosition?

If you want to show your spaceship infront of your background, you will have to adjust the zPosition to be higher than that of the background sprite.
