When I finished act 2 I had several set items. Chainmail and a couple of gloves at the least. When I started act 3 though they all changed to normal items? I asume that should not have happened.
Sorry, it has happened, Shadowchaser. Set/unique items loose their status due to act change, but keep their stats. They offer no additional bonus and can be sold in the next act, not the act where you find them. Kiya
