0.22 ref is now a quicksell price and doesn't happen all that often.

If the strange part is not in the buyers' backpacks, it means that they must have re-sold it for a higher price if they even got one in the first place (which then makes it a quicksell price).

"Quickbuyers buy to resell; they are rarely good evidence for a price decrease (though an abundance at the current value can show a price should be higher)"
