Well Santa Claus, queens breaking off their wings also has another benefit. Their wing muscles dissolve to give them the vital nutrients they need during the process of egg laying because they reduce their own feeding during this time. My guess is that the stress of 'keeping her wings' for your queen plus not having the energy which dissolving wing muscles provided collectively proved far too much for your lasius niger queen and this claimed her.
Furthermore, a person I once knew had a harvester ant queen who retained her wings. She layed eggs at first then suddenly stopped laying altogether and the colony crashed. Its pure speculation of keeping the wings seems to have adverse affects on some ant queens. Of course your queen's death could also been due to other causes such as unstable temperature, humidity and diet. Who knows.
