That's not a roll back. If it was rolled back, you would have got your items back too. You probably got trade hacked.

Items for trade:
Windhorn, Eagleforce, Doomfather, Grandbringer, Harlequin Gaze, Vampirecrest, Gladiator's Valor, Arkaine's Bane, and Shaftstart

Looking for Stone of Manald rings. Also, I want Hearld of Arreat and Zakarum's Face.
