Hello,
I have started SMN mythic "An Imperial Heist" by trading smn staff "Scepter Staff" to "Abquhbah" in Aht Urhgan Whitegate (I-10) then I have finished required 2 quest "Duties, Tasks, and Deeds" and "Forging a New Myth" but at the end on19-Oct-2017 "Palace Door in Aht Urhgan Whitegate" gave me Tizona which I already have it 119 II.
Please note that I already contacted SE support but they told me to call GM and GM told me to post the bug report.
Please help me as I have spent a lot of time and effort to do this quest.
Looking forward to upir support.
