This bug doesn\'t have anything to do with the updater or the game options. It is related to information coming from the server not being processed or lost AFAICS, because it affects random labels, including NSCs. If you relog, which label is displayed is randomised anew, which can rage from all to none.
When new players enter the area, or you enter a new area, it is also re-randomised for each person that comes into your area.
