It seams unless there is an error in the logic of this code, that after an actor has been deleted it still continues on in the log and gets recorded. See code example below in this version if you like.
..
It basically, drops the balloon (Actor test1), from the top then hits the line (Actor test2) , then the blue ball dissapears (Actor 1.
But then the ball still seams to be recording in the log until it hits the bottom like a (Ghost of the ball).
I would have thought it should record nothing and the Y pos of it hitting the line should be the last recorded.
