I have purchased 11 Mundus Stones for Topal Island, my primary residence. I need to purchase 3 more stonesfor completion of the set. I duplicated the Lord can I swap this out for a stone which I don't have?
I would submit a ticket and reply to the email you get from them with more information. I'm sure someone would be willing to help you out considering you spent so much money on the Mundus Stones. Just be nice to whoever is working with you and wait for their reply. Don't spam them with requests for an update as that moves you to the back of the line.
