What happened to my attack map?

[Gigalocus]

ever since i've installed 1.2, my attack map has become useless, i've lost the green line that says where the torps will run, everytime i go to attack, i follow the ship, overtake it, estimate its straight line, go to a perfect 90 degree angle, but with no green line, i fire my torps too early or late, so its not a good enough angle to explode, has it changed an otion in the realism settings? do i have to untick anything??

thanks - Gigalocus
