Only time I have had this issue has been when updating my subscription payment from a recurring crysta to a game time card, it would end up suspending my retainers if I don't go back and manually pay for them which has never made sense to me. But yeah.. If you've recently edited your payment options it might have kicked your retainers out of automatic renewal, and in the case of using a game time card, when you try to renew them, it'll attempt to charge you for the time period of the card so that you're paying for each retainer for 60 or 90 days or whatever, single payment, rather than monthly recurring. I've never seen it happen before with a monthly cc charge though I don't use that payment option due to chance of chargebacks...so I'd be checking with the bank to see if anything happened on their end.
