While working on some scenery recently I noticed that airport polygons for a certain area had completely disappeared, meaning that these airports become unusable because there is Autogen sticking out of the runways and taxiways!Does anyone know which file I should replace to get these back? (Not necessarily the specific one but where are the polygons stored)?ThanksJohn Holden

Hello John,Try the AB (airport background) files.Best regards.Luis

Thanks Luis.Turns out the bgl in question had been copied to AB***.0, with AB***.bgl being nothing but an empty file. Not sure how that happened.John
