This point has just occurred to me. Already I have seen several instances of fielders diving the wrong way when a ball approaches them, and also diving when the ball is nowhere near them. It has been a while since I played the game unpatched so I don't know if the original does this.
If this is to do with the shot having a greater range of trajectories, is this likely to be made worse by having a greater range of fielder positions as well.
I will try and capture a fielder diving out of the way when it next occurs. It is quite funny at first, but causes too many "unwanted" runs.
