Actor disappears if this behavior is turned on

I created an empty project,
added an actor,
dragged the actor onto scene,
added a accelerate towards behavior toward mouse position.
and if i preview it actor is gone
if i turned off the behavior actor is there when i preview.
What is up with that?

I had another similar problem too when I turned this off. and try to constrain actors rotation to a real variable. My actor also disappeared.
