NOT TOO IMPORTANT Null reference in Camera Shake. (#26)

[Bradels]

As now we are aware because of our scene loader.
When we load into a scene with a camera shake, we get an error.
Doesn't seem to affect the actual game however.

[Bradels]

1. Load a scene with a scene loader attacked. (Not sure if it not having a camera shake is important.)
2. Make the game load another scene with a "camera shake"
3. Trigger the camera shake, after completion.

NullReferenceException: Object reference not set to an instance of an object
