On the seller’s end, we see exactly 5 keys + 36 ref, but it doesn’t match with the next person in history. Most likely what happened is the buyer bought it, and gambled it away without their backpack being scanned. Will include this sale. Even if it were to be excluded, it wouldn’t affect the range anyways.
