I understand the lag time in payments, but have others been paid yet for blocks newer than 462711? It appears that all have "Matured" as of this writing except the top one, 462908 (which is currently at +96 confirms).
Maybe a block hasn't been found since they matured? If so the next Kano block found will process the 0 fee transaction, unless some other pool is feeling altruistic and processes it first.
