I've bought a bunch of items from the Steamworks Menagerie and used quickstock to place them all in my wardrobe. I check account search and the items are there, but they won't show up when I try to load the wardrobe.
Is this normal?
Yeah sometimes it takes a while for them to show up.
If you want to work with it now, check 'All Items', search for said item and put it on. Saving that outfit won't give you an error because the item is already in your wardrobe, it just doesn't show up yet.
