Basic Project of a graphic with 5 layers parented from top to bottom black with white back ground. Simple tween from left to right, turn around and then right to left across the screen. I can get the tween to go one direction and turn the graphic around with mirror horizontal. Then the program crashes, closes spontaneously no error or crash report noted, when I tween back from right to left. It has done this four times now in the same spot any help would be great.
