When I checked the "All Games" page today, it redirected to the "All Categories" page with an empty notfound parameter. Does this mean the "All Games" page is being redesigned and being replaced with this redirect during the redesign, or is it a new bug?
Edit: It looks like the notfound parameter is used when a search for a non-existent category is redirected to the "All Categories" page. That means the "All Games" page is being treated as a search for an empty category.
