I never imagined I would ask your help about FREDing, but FS1 causes some problems> It suddenly quits from the mission into the windows.
I suppose it is the problem of FREDing, because it occurs only in the case of my missions. Except the 'The Big Bang' mission, which also quits sometimes, and you surely know it is the mission when a Faustus has the Tsunami plan onboard and must be defended. It quits sometimes, but not as often as my missions. I suppose it is because the large number of ships in the area, but I am not certain since FS quited while I was fighting the last remained fighter alone, and we two were in the area alone.
Otherwise If I want to restart the game after this kind of quiting, I would have to restart my machine. . . . . Illegal operation window appears.
