My charachter was deleted?

[Thetok]

Hi!
I started playing yestertay, got 10 lvl on my human warlock, but now I see clear charachter's page! My warlock disappeared
Was there any blue post about it?

How often such huge rolls back happen? Should I start lvling again today or its better to wait а few days?

So it seems I chose very unfortunate moment to start playing? )
