I used to play WOTLK on Icecrown and I stopped around July 2017. I decided to check what's happening there again and I saw that all my characters have been deleted. I had a 80lvl boomie and mage, both above 6k gear. I have my two factor authentication on and I received a couple of times emails to confirm that I am logging in (it was not me) so I changed my password a few times just to keep my account safe. What happened to my characters and how can I get them back?
