I've noticed with some couple of last bingos that there is "transition period", if you could call it that, when Bingo has officially ended and you are not able to access it, but all the buttons to Bingo are still there. At this time such error message appears. I assume it's due to time zones or something. So by your time zone the Bingo has already ended, but due to other time zones in which players are still able to access Bingo, TinyCo can't remove the Bingo buttons yet. I think this would be more clear if they just introduced other error message saying something like "Sorry, Bingo has ended" or something.
