It appears the fighter bay problem is caused by a simple error of not naming the race correctly in the fighter bay file (fb_gorith.ini). It refers to "Narn" rather than "Narn Regime" which is the name of the race. Correcting that should make it work.
Whoa, it finally works!!! Fingers, you are truly the man that makes things work! Huge thanks for your help with that problem.
Only one word missing that made so many people desparate.
I hope Psientist wouldn't mind if I upload the revised file " fb_gorith.ini". Copy it into "\...\Weird Worlds\B5_Shadowfall\gamedata\items" and replace the old file.
Added comment: Looking at the quest.ini file I see lots of events that I have never come across in my many games of Shadowfall. Am I the only one thinking that most of the quests are broken?
In the large map setting, the Vorlon, Shadows and the planet killer don't show up, even if the quests come up. I think it's been suggested that it may be a limitation on the number of ships.
