Many Team Fortress 2 players are either currently having their best day or worst day, depending on who you ask, as the rarest commodity in the game's economy, Unusual Hats, have suddenly become a common drop from Supply Crates (loot crates).
Following a small update to the game that was pushed by Valve yesterday on July 25, players have found some Supply Crates are dropping Unusual quality items 100% of the time. These items are a 1% drop normally, and go for hundreds to even thousands of dollars in both the Steam Community Market and other trading websites.
Looking into the Community Market right now, crates that were selling for $0.03 are now soaring in the $10-15 range. Meanwhile, many Unusuals that were dealing in the hundreds of dollars, have now fallen to $5-10 ranges. For instance, one Unusual Modest Pile of Hat item sold for $770 on June 26, but now it can be had for just around $10. Not a good day for those who've purchased these items for lavish prices previously.
Popular third-party trading websites, like Scrap.TF, have also been affected, with them disabling several Unusual Item related features. Even the Team Fortress 2 subreddit has been locked down until the "economy situation is resolved."
We will have to wait and see what Valve does regarding this absurd situation when the relevant development team realizes what that small update has done. We expect to see quite a lot of rollbacks and refunds.
UPDATE: Valve has now disabled trading and marketing of all the "bugged Unusuals", and the affected crates have also now gone back to their original drop chances. This is only a first step, however, as the company is waiting until after the weekend to tackle the item situation fully.
