Do you lose track of the target? Since the Sparrow is a SARH-missile, you need a constant radar lock until it hits the target. It is quite easy for someone to make you lose your lock, all they need to do is notch your radar, going perpendicular, or 90 degrees to you. Since your radar uses pulse Doppler to find targets, it is impossible for it to see something that is going 90 degrees to the radar since PD only looks for a speed difference between you and the target. I hope this helped!

I have the same issue the rocket just flies past its locked target. I would assume its a bug
