Layout bugs Gamespot UK

Over the last few days I've noticed on almost every page has major layout bugs for the gamespot UK site. Most notably the banner and navigation disappearing, large spaces above comments and the emblems on the user page are messed up.

Probably a CSS cockup.

This must be a known problem? Right?

I found out that a few of the problems are because of the layouts poor handling of zooming in or out.

Though one bug has nothing to do with this, the PC (maybe others) main page the top is missing. Maybe something to do with the Rift ad.

Edit: I've firebugged it and it's all still there, I think the rift background must be z-indexed above it.

Edit2: I added a lower z-index to it and I was right, it's covering the masthead.
