Speichern meldet Fehler und schützt unbrauchbare Stände

Browse Source 
Lässt sich ein unbrauchbarer Spielstand nicht beiseitelegen, bleibt das
Speichern gesperrt, bis ein Stand erfolgreich geladen wird; so wird er
nie überschrieben. Ein gescheitertes automatisches Speichern zeigt
SAVE_FAILED, und jedes gescheiterte Speichern wird protokolliert.
