I am having the same problem after the update with the clouds. The problem is not present all the time. The missile even in STT goes straight (F16)!
I will try to add track file later.
There is a bug in AIM 120. Even if you launch in TWS the enemy hear the warning immediately. This is true in F16 AND F18.
...and I was happy with DL.
...update...This is true only for the F18
