For some reason I'm not able to actually equip any of the 3 new EoA skins on my Elite units. I see them displayed as swatches/tiles in the Elites menu, alongside other skins for that unit, but when I click on them I get the same sound I would if I clicked one of the other skins I haven't unlocked, and nothing else happens. When I view the details of a particular Elite unit I can then select the skin (e.g., Dark Queen) but after exiting that view it's not equipped. Same for the other races. Any insight?
