How does this work? What if you want to remove an AtlasSprites from the the AtlasSpriteManager?

Is it the same case? Is there no way to remove them?

We never manually remove our AtlasSpriteManager objects since they are children of the Scene (in our case) and so they get removed automatically when the Scene gets removed. You shouldn't have to do any of the above code.

Is it possible you called release on the atlas manager explicitly at some point?

Should i remove atlasSpriteManager from my gameScene to avoid memory leaks?
If so why can this piece of code cause crash?

if (m_atlasMngr) {
[m_atlasMngr stopAllActions];
[m_playerSprite stopAllActions];
[m_atlasMngr removeChild:m_playerSprite cleanup:YES];
[m_gameScene removeChild:m_atlasMngr cleanup:YES];
m_atlasMngr = nil;
m_playerSprite = nil;
}

It crashes when i'm trying to remove manager from scene.
