I'm just learning how to mod and have definitely hit the 'knows enough to be dangerous' stage.
GC II:DA. I was trying to substitute the Centauri Republic from B5 for the Altarians. Seemed natural enough. It seemed to work, except somehow the Drengin also show up as the Centauri. I tried to just reverse what I did and start over with the backup file I saved, but no luck. Aft4er some tinkering around, I even uninstalled the game, deleted the Gc2 directory, and reinstalled. And the Drengin still show as the Centauri. though the Race Config file clearly has them as the Drengin. And DL shows them as the Drengin. Where else might this have been changed?
