It´s ok that you have nerfed the way to score by headers. But it´s not possible that even just a passing header in the right direction ends with the ball going anywhere but where you pointed. It´s just insane. If in order to nerf goals scored by headers you have just nerfed any kind of header you are doing wrong or probably your developer skills are not just good for a game like this. If it continues like this just remove players' heads because it´s the same if they have it or not.
