ball over bouncing with restitution 1

Hello


I am trying to simulate an infinite bouncing ball with restitution 1.0, linear damping 0, friction 0, does not allow rotation, angular damping 0. However when the ball hits a block with similar physics attributes it bounces to extra height, which is wierd.


Note: This error only occurs when the initial distance between the ball and block is low, with higher initial distance their is no extra bounce. Also, the ball starts with zero velocity.


Please help.
