I just tried to redeem points for the dinner buffet at the Mirage and I received this message-"Your purchase limit for this reward has been reached" I was denied the reward. I have only redeem one reward since I have been playing this game. I redeemed this same reward in December of 2013. Is there a limit on how many rewards that can be redeemed in a 12 month period? I thought there was a three month limit. Am I missing something or has the game become that tight?
