Yes there is. Zombie persistence. If you are allowed to drive off from a quest at will, zombies will despawn and quest will be fukked. So what is it you are really asking? Be safe from a clear/fetch quest for eternity by just "run away" and "coming back"? Or make the game force you to stay within boundaries while clearly stating met objectives in UI and meet the challange? My only argument againts op is, he "forgets" what the objectives are and are clearly IN YOUR FACE while doing any guests. Apart from any ADD, ADHD or Autism arguments, there is no argument. You get a mission stating what are objectives. And when you activate mision the objectives are IN YOUR FACE all the time in UI. So im not downplaying you in any way or any mentally changellenged players. But thats not the argument of OP. He just covers eyes and ears and says, game should compensate. I wholeheartedly disagree with that. But thats just an IMO with arguments. Oppossed to the personal attacks from OP without ANY argument. Peace brother.
