Anyone else experiencing this? Clicking on "view stats" on my listing brings up the usual "US States Traded" page. If I want to view the breakdown in my collection (by platform, type, etc) all sub-options work expect "available and collection", which brings up the US States page again. Same issue on mobile (when viewing the non-mobile site -- I don't believe the mobile site has this feature built in).
Sometimes I use this to see how many games I have total (although I suppose I could view "available" and "collection" separately and add them up).
This feature is awesome BTW!
