FM bug after firing single rail Aim-9X from outer pylon

[HWasp]

When using the single Aim-9X on the outer pylon, firing one of them results in extreme roll moments. This does not occur with the double pylons and other loadouts.

 

In the attached track I have used nose up elevator with no roll input to check the behaviour, which, as you can see, resulted in a barrel roll after firing the Aim-9X.
