What are you standing there for??

Hi guys. I have been gone for a bit but now I am back playing. My question is this, why aren't the enemies attacking me? I mean, if I attack them, they do. But I can bump into them, stand right in front of them and nothing. It used to be that if I was surrounded by baddies they would attack. Not anymore. I know it might sound strange to some of you, but it takes the thrill out of racing through a bunch of bad guys knowing they won't even react at all. Is it just my game or a universal thing now?
