I'm using the newest beta version of the wardrobe, but I cannot seem to save outfits that are in progress (as in, I'm building them in the wardrobe but not actively wearing them). Clicking the "Save Outfit" button underneath the HA preview in the center doesn't seem to do anything, and going to the Outfits tab and clicking "Save Current Outfit" only saves what I'm wearing onsite not what is currently in progress on my HA in the Avatar tab.
I'm considering this a bug because we used to be able to save outfits with items we didn't own yet or weren't actually wearing onsite. It's nice to be able to save outfits that you're still working on to come back to later when you have more ideas.
