when using more than one behaviour in my scene (e.g. GazePointVisualizer in your GazeAware3DScene-Example) and testing it in the gameview of Unity, i´m getting the following error which also crashes the program.
Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)
The error doesn´t appear though, when i buid&run the program.
