It is not disappearing off the screen for me. Its where you have it in the editor. I'm not certain whats happening. but did you try the anchor behavior?
Yeah its not disapearing because its set to parallax(0,0), but the wheel doesnt functions properly, it doesnt rotate to where you are clicking or touching.
Only if you set the layer to parallax(100,100) the wheel works correctly, but it disapears offscreen
