Missing Cosmetics from Inventory fix
Okay so I don't know if this is a widespread bug or not, but once you complete the Bot Matches all of your cosmetics will be reset. That's not the issue though it has been acknowledged and a fix being looked into, thankfully.
No, sometimes you may open your inventory on a character and just find cosmetics missing. For me, it was my Wraith- I had none of the head pieces in my Inventory (including prestige despite being P350).
To fix this, go into the store, filters, show all items, and then you should see your entire stock of items. Equipping one will return the rest of the missing ones.
