- Create a new scene in any project
- Try to add a Reflection Probe component to the Main Camera
You get immediately prompted to save the scene. Try to Cancel. You can't! You get the same prompt again.

My guess is that this happens because we try to Bake the probe as soon as the component is added. Since there is a Bake button in the component, I think this should be changed so that the Component can be added to the GameObject and only when the user presses the Bake button the Save Scene prompt should pop up.
