None of the tutorials work for some reason. I follow all the steps, but he never lays a finger on the person. They do some elaborate flips and things, but nothing happened to the other person. Something must be wrong.
Very small alterations have been made to the physics as far as I know, but nothing too big. As has been said already, the engage distance is the problem with the move you were trying. Somehow, it got changed from its default. Have a go at changing the engage distance to 100 before you start the tutorial. That might just do it.
