This happens on the mission after the aquitaine is destroyed.  Any idea what it means?  Running 3.6.7 with media VPs and no other mods, with a fresh pilot to boot.
And, I did have the tempest as primaries problem in the first mission, but I just did the infinite ammo exploit and cheated my way through it
