Its easier to watch the clip but...I'll try and explain.
So the player going for the ball suffers a GFI. reroll and he moves to the position of the ball. The highlight is there but the ball ceases to exist on the field. No roll is made for him to pick up the ball. The AI team continues and blitzes another member of my team. After this move is complete the ball magically reappears and the GFI player fails to pick up the ball resulting in a turnover. Due to the order of operations failure the AI team was allowed a blitz it should never have been able to do.
