I have had this happen a couple of times this week. One time against a cheeser, but I also had it happen against a normal player.
Runner takes a massive lead; I mean at least 3 steps. I throw to first and the runner instantly takes off for the next base, but for some reason he is literally 3/4 of the way to the next base before the ball even reaches the fielder.
Is this yet another glitch that can be exploited by cheesers? If it is I might not be as eager to throw over on the overly aggressive lead, because I have gotten very good at picking runners off. I even had a guy quit after I got him twice in 3 innings.
