NullReferenceException UnityEditor.HandleUtility+SavedCamera..ctor (UnityEngine.Camera source) UnityEditor.HandleUtility.PushCamera (UnityEngine.Camera camera) UnityEditor.SceneViewRotation.OnGUI () i get these all the time and i have no idea why. what are they and how can i avoid them?
If you double click the error it usually brings up the script that caused the error. If you have the error all the time even with no scripts you might have a bug and should post a bug report or try reinstalling. If it's a script error edit your post with it and we'll take a look.
This seems to happen when the Main Camera is moved to become a child of another Game Object..
