Never had a problem with transmog across multiple characters until I spent money on one for the first time with my barb (I think it’s called the “Spoils of War” set).
Now transmog is super buggy/broken. Sometimes I can switch to the new outfit for a few minutes before it reverts back to what I had before. Sometimes even while I’m on the wardrobe screen it will switch certain items back when I click into others, or randomly change the color of certain items.
Incredibly frustrating when I finally made the leap to spend almost HALF AS MUCH as the game itself for a blasted outfit, and turns out purchased outfits straight up don’t work. You’d think with astronomical outfit prices like these, Blizzard could actually make them work at least.
