Did boss arena, got banned for hacking...?

It might be unrelated. Auto-Bans are normally instant. What were you doing when you got the ban?

(Or it might be some kind of memory corruption which made your client behave strangely enough to trigger the auto-ban.)

Went to grind, was about 3 minutes into training..

Update : i logged a ticket, and for once wasnt all nice and kissass about it. Basically chewed out whoever it was that tried to ban me haha. They responded to my ticket within 20 minutes (record time in all my years of playing) and said they apologize and are unlocking my account and reviewed my account information and saw that I was falsely banned. So who knows what the reason could have been.
