Thanks Dimitris. I was playing the steam version and 1307.13 is the latest version for now. I've manually updated it to 1307.14 and hope it get solved.

I have struggles with PL-15 missile when playing PLAA
The missile travel at 62k ft all the way towards target no matter what altitude the target is. as the target plane always took dive, the missile will just fly past the target then decrease altitude.

PL-12 seems alright with its arc of travel ...
