Hey, i added several reserve drivers in my create a team save. First 2 armstrong and vips. Had to unretire them and gave them superlicence. Fired my 2 reserves via deleting contract in game. Cant use a driver in fp1. Button does nothing. No drivers where shown. Than i tried adding actual drivers. Enzo firtipaldi and sebastian montoya and david schumacher. Cant choose any of them in fp1 to. Tried to experiment with superlicence. Didn't help. 2nd thing i recognized. After addiding the new drivers, my reserve only shows the last 3 i added. i can find armstrong and vips via scouting. They are still shown as in my team.

Ok, here If i go back to an older save. Vips and armstrong are added. Caterina Martini and fracois guillot the initial random reserves are still in. Now i can choose any of them in fp1. If i fire catarina i cant choose a reserve driver in fp1. If i fire gulliot, i can choose only Caterina. Both drivers have no licence in db editor and i changed their salery in db editor at some point if that matters

I think its a bug in the game. If i hire 2 drivers via immediate offer its all good as long i dont fire the 2 random reserves
