Comment (by teor):

 I wonder if this can happen when a relay wakes up from hibernation after a
 week or two?

 168 hours isn't very old for a microdesc any more: Tor relays used to
 change their onion keys every 7 days, forcing a microdesc hash change
 every week. But now, the expired microdesc can be listed in the new
 consensus after hibernation, because the onion keys only change every 30
 days.

 Maybe this isn't the issue, but it seems like it might be worth looking
 into.
