You can see that the shutter shades are “equipped” but not actually displayed on my character.
However, if you go into a game, all items will appear in-game correctly. This bug only causes your 2D character image to not have all items displayed correctly. (the 3D view is fine)
It happens at random (and the number of items impacted is random), but it’s fairly frequent and easy to repro if you change between outfits containing lots of items. It will be fine again if you change into the outfit once or twice more.
I’m on Chrome, Windows 10, and this happens with no extensions running.
