Your item is duplicated, unlucky for you.
If your item is on vault, take all your stuff from there, and leave only the duplicated item, aka duped, and go to
www.infinitymu.net and reset your vault.
If it is on your inventory, take all you equipped stuff, rings, everything, and to to
www.infinitymu.net, login, and reset you inventory.
If it is too hard for you, or you don't understand, wait for an admin to help you out.
Good Luck Man ;x
