We just had a similar data error reported via trac where another change
was dropped within the same hour as this changeset:

https://trac.openstreetmap.org/ticket/4591 

I looked back through various logs and it seems the machine holding the
rendering database was rebooted at this time. There was an error
applying the first 30 minutely replication diffs when it came back up.
It is not clear why this happened.

There is an intention to reload the Mapnik rendering database with the
ODBL planet file and this will fix these inconsistencies. I don't have
an estimate of when this will be done.
