SKShapeNode producing crash sometimes on dealloc EXC_BAD_ACCESS

Question

In my main scene I create 4 walls with this method:

-(void)createFirstWalls{

    CGFloat maxY = CGRectGetMaxY(self.frame);
    Wall* wall1=[Wall wallWithRect:se

It seems to be a bug with the SKShapeNode in iOS 7.1 ...

But finally I found the answer!!! Hope this can help more people.

I implemented a method to remove all the childs in the current node

- (void)cleanUpChildrenAndRemove:(SKNode*)node {
    for (SKNode *child in node.children) {
        [self cleanUpChildrenAndRemove:child];
    }
    [node removeFromParent];
}

And then call that function before I present a new scene

    [self cleanUpChildrenAndRemove:self]; //god bless this method
    SKScene* gameOver =[GameOver sceneWithSize:self.view.bounds.size];
    gameOver.scaleMode = SKSceneScaleModeAspectFill;
    [self.view presentScene:gameOver];

No more crashes nor BAD_EXC... A true miracle.
