When an objects is sitting on top of another, and you remove the box without actually pushing (for example you just delete the bottom object) it does not update the top object, and the object just floats there until touched or bumped by another object.

Are you using physics behavior? Is it a 2D game? You need to explain in more detail and share screenshoots (especially of the related events).
Its using the 3D physics behavior, I can’t take screenshot right now, but I can tomorrow
