In 2 play throughs ive scoured large quadrants of sectors(not really a quarter if the galaxy, that would be insane for this.) and not once have i seen a fighter factory, though ive seen many turret factories and all other station types.
Whats further interesting, is that when i have an exploration captain scout a quadrant, and then i look at the station sectors that its scouted in the map screen, i can find sectors that say they have fighter factories in them, but when i actually go to those sectors to go the station, the game seems to replace that station with another type of station, leaving all other stations in that sector alone.

So to the chase, my question is are the fighter factories no more or are they waaay rarer than usual, and my game is just bugging ou?
