the Unlocked Cosmetic Crate's are assigned to the action slot but have no classes assigned to them so they cannot be equipped by any class, they are technically equipable using tricks in item test, this might be an oversight, this will fix it to where they are assigned classes so they can be equipped, the multi class crate can be equipped by all classes but it would be funny if the unlocked crates that are class specific were only equipable for the classes they were for.
