VfB Oldenburg has the semi-professional status in the game. However, as far as I know at least, in Germany you are considered a professional club when you successfully join the lowest professional league (3. Liga), which they did. There is no indicator that VfB Oldenburg is working under other circumstances then the other clubs in the league. Now in FM the semi-professional status means that you cannot utilize training for more then 2 days etc., which is simply not the case in real life and very annoying in game.
Is this status a bug or is there some other reason behind it?
