I thought characters were not restored due to the policy Nostalrius had, not due to technical reasons. Also, I found it odd that I got my character, with the same name and physical features but only lvl 3 (what backup is that, from August 2015?).
Anyway, I know the Elysium team has a ton of issues to solve now, but i thought i might ask... a lot of effort was put on that character before my (foolishly) deleting him and I don't know if I'll have the patience to start all over again.
