As title suggests, the game runs fine (and is awesome!) but replays don't work properly. By this, I mean that they are constantly and always stuttering, flashing, and freezing. There is never a moment where it runs smoothly or normally at all. And this happens at any speed. Just saying, the replay mode could probably use some optimization or something--I am not running this on a crappy laptop (though it isn't a gaming laptop, it can still run a lot of stuff!)
