If this was another MMO, the GM would have deemed your achievements and quest completion as enough evidence to send you your relic back. I also believe they keep some sort of record of myth earned/spent, so the GM may also be able to restore your AFv2 without actually having to roll it back to a certain day. In other games, GMs will review your account and then in-game MAIL you the missing items. This is their go-to solution when quests are bugged, can't be completed, etc. It gives the dev team some time to fix the bugs while the GMs provide the 'quick fix' to affected players. A lack of GM response or tools to help players has resulted in a HUGE list of tickets that GMs really don't have the time to answer directly. The best you'll get is something generic. With all the money this game is generating, I can only assume that more GMs will be hired and their system will be altered in some way...

Now, I'm curious... why did you log in when the restoration was under way? I would have been way too paranoid to log in before I received the "Your account has been restored" e-mail because something bad might happen if you interrupt the process. o.o;;

Also, food for thought. Which exact date did you give for the restoration? It's possible the people who hacked your account took control of it that day, logged in, and dumped all of your 'unnecessary' gear to make room for all the stuff they would farm. This seems odd considering the armory chest is 'separate', but this is what hackers do in other MMOs.. they destroy all your gear but gear needed to farm. Although I do remember this one time... My account was hacked in WoW (YEARS after I had last played... no idea who got my password or how since I don't use it for anything else and the last time I logged in was 2+ years prior). Everything was restored -- except my gear. I couldn't find it anywhere. It was really bothering me because everything I had were aesthetic pieces for the memories. Then I looked in the bank... The hacker, instead of dropping or disenchanting my gear, dumped ALL of my gear in the bank for safe keeping. o.O;;
