Resold for a MG Toy Soldier (outdated at 38), which was then flipped for a Stormy Neckwear (42.5), and later traded for a Mallard Practitioner (outdated at 30)

So the buyer in the Overclocked Modest sale went from 58 keys in mixed to a hat outdated at 30 in like a day. I don't think any of those sales represent a common trading point, so this should stay outdated.
