I set the sniping at 5 seconds, but BidSlammer sniped it at an hour prior auction end. I also didn't win the bid, but BidSlammer thinks I did.

Hello James,
Thank you for your question about the bidding time. It appears the refresh got behind due to the number of refreshes in the queue, so it didn't update the time. We are making a change so this will not happen in the future. Thanks for bringing it to our attention.
Please let us know if you have any other questions, or require other assistance. We are happy to help.
