"We will continue to carefully investigate and address the causes of these types of occurrences. We still have the lottery data, and it is possible for us to confirm the status of entry applications through our database server logs. These logs will be referenced to ensure that players who have accepted their gil refund from losing the lottery will not be negatively affected by the measures we will be taking afterwards. We apologize for the inconvenience caused by these issues, but please rest assured regarding this point."

I don't know about you, but this sounds to me like after an emergency maintenance, a client update and a measure implemented to ensure a player is billed correctly if they took their bid out, people who won the bid but 'lost' to the "0" bug including solo bidders will get their house.
