The target is close enough for a good tone, that's all I know for now. Maybe the problem is that I get a good tone but I don't look at how far away the target is, so that's maybe why it doesn't track. But it doesn't track at all, it just launches off of my wing and goes forward, not even turning towards the target. Also I'm pretty sure that the problem is with the Aim-120 (I forgot what variant). When I get a good lock onto the target and I know that I am well in range it still doesn't track. A couple months back it always worked, for any missile I launched on a multiplayer server. Now it just doesn't. Maybe I'm forgetting to turn on something while cold starting the plane, or turning on additional buttons while hot starting.
