i think i found problem. it is not directly related Playmaker. i had known that unity inspectors cause glitch on Physics Engine, so i always deselect objects before playing it on editor. this time Playmaker Globals window caused this problem. when an active window updates it values it cause update problem on game window. in this case i select another tab in the section that Globals in, i works fine. so solution is; select nothing, close or hide all editor windows that updates themselves with game object play.
