According to the official blog post, ”Due to issues beyond our control, I am sorry to have to inform all of Atlantic that we had to revert to a Dec 5, 2012 7:00 am EST back up. We have tried to retrieve a more current back up but we have been unable to do so due to corruption issues. We are very sorry this has happened and any Atlantic player that is being impacted by this revert will be compensated with 30 days free game time. If you are having any issues with Vet Rewards or In game codes please page a GM. They will be able to assist you with this matter but please provide what vet reward/code was claimed and by what character to help us confirm your request faster.”
Ouch - two weeks worth of grinding gone.
