My Myth piece "Valor Cuisses" is gone from my armory when I equipped Heavy Allagan Cuisses.

I used right click, equip method from the Armory itself. I was inside Coil Turn 2 at the time. Just completed turn 2 and was equipping it in advance for moving to turn 4.

Heavy Allagan Cuisses did equip but Valor Cuisses did not return to my Armory.

I am so annoyed as that took 3 weeks to save up 825 Myth and was my coil accuracy piece.

This happened before on my Garuda Bow but I didnt really need it so I did not log it as a bug, but NOW that its happened to my myth legs I am not happy at all. Please check my gear as I had them on me when I entered coil. Can you please look into this ASAP?????
