Relevant for latest update Also all the codes make up at least one PNG image (but likely one image for each 'error', with the 'codes' for each error making up the image).
The weird banana errors were decoded by tf community, they are QR codes. 8 banana errors = 8 QR codes.
In a pre-emptive strike against the 10,000 post limit (and because I need sleep eventually), here's a new OP! Tuesday: Valve adds 7 mysterious items that randomly drop and serve no purpose! Wednesday: Valve adds a special attribute to the Eliminate the Impossible (Medic Sherlock Holmes) set that causes the descriptions of the previous day to change into a quote from "The Adventure of the Copper Beeches" a Sherlock Holmes story. Thursday: Valve adds an error code when crafting two banana peels. Each code shows a specific error, which, when pieced together, is assumed to form 4 QR codes that lead to images Code 1 leads to: http://tf2.com/tn125a5ym6sn.jpg Code 2 leads to: http://tf2.com/9rpragt86n3p.jpg Code 4 leads to: http://tf2.com/h5r1bxdt9sg1.jpg QR Code 7/8 (they're the same) leads to this: http://tf2.com/cajtaypvdbyl.jpg cosmic duck posted: The server might cache this thread if many more people start viewing the thread.

Clues all over the maps of the number "22' AFTER 10 HOURS MEET THE PYRO WILL BE RELEASED. then we also found this: some people think that the pyro is poopy joe.

Well, that probably means that we're getting Meet the Pyro on Monday or Valve is gonna continue the treasure hunt.
Well, the Schorch Shot (two links) for one, as I mentioned - with a mic! - on #7. It was revealed the moment those hidden codes (from the Banana crafting) were decoded, or so I've read. That's the only thing we know (as of about 9 hours ago, I don't know if there was an update when I was asleep).
