The item updating system is automated, and I need to explain something.

Items that are completely untradeable (such as brand new promo items, golden wrenches, etc) are filtered out of the search and new trade page listings to help keep the list of items shorter and more organised/sensible. Therefore, I can't add them to the listing as they technically break my own rules and why would you even want to be able to search for completly untradeable + ungiftable items anyway?

I wasn't aware of this, and I haven't bought any untradeable items either. Sorry. ;_;
