Note on the cosmetic chest, you can get items that you have already traded in... so anyone who has got the captain headguard (for example) and traded it in but can still use the cosmetic can still receive it in a cosmetic chest... I don't think this is fair as there was no use for the items before the cosmetic chest was introduced and now we have to work our way through endless dupes to fill our collections. We should at least get the cosmetics we had or take them out of the reward selection.
