So I'm playing career mode. Sometimes in the middle of a game, one of my half back players will just sprint to get ahead of the ball and run into the forward line and line up next to my full forward with no regard for his direct opponent. I messed around the tactics and set it so no backline player can play ahead of the ball. But he will still just charge into my forward 50 leaving a free man inside my defensive 50. Once it happens once in a game, it will continue to happen for the rest of game, even at center bounces. Once it's bounced, the player will just leave his opponent and sprint forward.
It's not a huge issue but it has cost me a game or two and would hate for it to cost me a grand final.
