They broke the cops again... They're very angry now, and be careful when you blow past them. If you whip your car around the corner now, they instantly aggro with a wanted level, and from then on the static ones will attack on sight if they were in the daisy chain of your egress while under wanted status.
I broke an entire block because I circled around while wanted, passed by static pigs, hid, then waited. After that point in time, every time I pass the threshold of their supposed perception block, I enter a state of combat, get wanted, and the same pigs want my blood whether or not I've done anything; essentially, they are stuck. Also, killing static cops will keep their bodies in the world, and the only way to get around this is to progress the story past a loading screen. This is hard to do since there are hardly any loading screens in the game. Just be careful until they fix this bug, and yes they are now aware of the issue through bug reports and emails.
Just wish they didn't have to break the existing game to fix it; it makes it feel very beta right now with some of the new bugs. If the only thing they accomplish next year is an overhaul to the police system, making them at least fightable in every sense (quickhacks please), and the only real threat was Maxtac, I would be happy. The game is very difficult to play when you don't know what you can and can't get away with because suddenly all of the police are insane and angry.
