People put bids on the previous version of this adopt from you, didn't they win it?

Open

I go in after the auction ends and it just isn't there, apparently the site is slow since the account is new

The old auction can still be seen in your archives. It usually always takes a lil bit before the messages pop up that the auction really has ended. I would've personally suggested to give it a hot second before you re-posted for the original winner of the auction to get in contact. Hope you won't get in trouble because of this :(
