value. The incident has been nicknamed "The Crate Depression" (a pun on "Crate" and "The Great Depression") by fans. On July 26, 2019, this bug was fixed. Users who received any Unusual-grade cosmetic items from the bug were restricted from trading them, with Valve later announcing in an official statement on August 2, 2019 that the first Unusual-grade item any player received from the bug is tradable, with any subsequent Unusual-grade items being permanently untradeable and only usable by the player who received them.
