New update for those of you following this story

We have established contact with the previously-AWOL owner, and after much discussion, we have determined that while there was an error in the auto-payment initially, the renewal funds were transferred manually to Sav and the auction continues despite that. We are currently appealing to Sav support with our domain credentials. We are also looking into whether an ICANN-compliant grace period was implemented prior to the rescinding and auctioning of the domain.
