It used to be that if you had global visibility enabled in the wardrobe, items you already owned would be highlighted. That doesn't seem to be the case any more, is there an option somewhere I'm not seeing?

I want to search through all non-CWs to see what I have already (I'm grinding for the Filled Wardrobe achievement) and I really, really, really do not want to have to do individual account searches via Subetalodge for every single item.

you're not missing anything. There have been a lot of wardrobe changes - they make a change and it breaks something, so they revert it. Or it causes too much lag. Or some other reason, so a lot of features have come and gone. They may be back, if they can figure out how to solve the problem it caused, or it may be gone for good.

At this time, there is no easy way to do what you want within the wardrobe.

Your best bet is to mass add your wardrobe to the subetaLodge wardrobe checklist and work from there.

urgh, I was afraid of that. Thanks. Should have done more when I had the chance I guess.
