I've tried to recreate the problem but it works fine which is just typical. I can't figure out what the difference between my game and the example is! Maybe someone will have an idea if I post a video of the issue...

Here you can see my football player kicking the ball to knocktraffic cones over. When the cones fall down they should be alpha 0.5. At first the alpha doesn't change but when I move the player into a specific area (lower right) the alpha takes effect. The sweet spot that causes the alpha to take effect is different every time I play.
I'm not sure if it's the camera position causing the change or the player/ball position. I hope the video is clear enough to see.
