Hey there @TheNorfolkian . The team is aware of an issue where the set becomes available for purchase again if you'd altered your first set in any way at the Blacksmith. Since you mention that you have fully upgraded your first set of the Gear, this would be why you're seeing it again. This issue will also cause your altered or upgraded gear to revert back to it's original appearance if you purchase and equip a second set of the gear, so I would recommend not purchasing a second set for now.
