Okay, I have played on and off for a few years and just started back. I downloaded and am running 7. 1 right now, and I've run into an issue with the PDC and Hangars. I put in 3000 tons of Hangar Bay (i. e. 3 bays), but when I tried to assign 3 490 Ton Fighters to it, I was told there wasn't sufficient hangar bay available. I also had 102 Flight Crew quarters, so I know there was room there as well. What am I missing?
