At least they are for me anyways. I can't hover over items to get the preview/description, and I can't hover over other users to see their info either.

Any time I try or just accidentally happen to mouse over one of the mentioned, it re-routs me to this url: http://subeta.net/styles/semantic/images/loader-medium.gifstyles/subeta/topleft.png

and it just says: 404 Not Found nginx/1.4.4

I've tried clearing cache and cookies and all that good stuff, and restarting my laptop. I use Windows 8.1 and Mozilla Firefox.
