Pretty sure this is all related to the original issue: there's too many items on your account for the page to properly load and calculate so you get an error of some type. Sorry guys. :(

Staff are trying to figure out a way to get this to work, but it just takes up too much resources.

The page has been removed.

This feature has been a problem for a really long time, and there is no easy solution. I'd challenge you to find another site the lets you see all of the tens (or hundreds) of thousands of items that you have in your account, each with it's price. It's just not easy to do, and it's not good for our servers.

I've removed it from the header menu, and retired the achievement that goes along with it.

I'm going to go ahead and lock this up since it's been removed.
