What search engine are you referring to?
The ability to search for skins.
If you type in skin names like 'Fabre' for instance, it will return 'No results found'.
(*Tried to post image but forums won't let me?)
If you Google Fabre Windowblind, you get the link to the WC page it is on.
This tends to happen with older skins, but you would be surprised how many skins done within the past few years this happens with. Not only does the windowblind not come up but it doesn't show the Rainy's, docks, etc. In some cases, you get the windowblind but none of the other matching skins that ARE in the WC gallery.
