Are you sure your perks have vanished? I took a look within your account and you seem to have all the perks. For example, your quests do say max 15 each, and I see you've also completed 15 each of Carl, Wizard, and Saggi today.

[edit] Or wait, did you already buy a new GA and that fixed it? If so, please file a ticket, we'll verify this and are happy to reimburse you with 3 extra days of free GA for the days you lost.
