I pay my accounts twice a year, by game time cards now because that's easier, but I have a credit card backup as well. I don't think the age of my accounts are tied to that because if it were, I would be getting awards at the same time every year - now and in January. Indeed, most of my accounts were paid last month. In March (I think it was March), one of my 5 accounts did get a vet reward gump. The other 4 seem to be stuck. I'll put in a bug report tonight when I log in.
