For me Ynosvt bid was placed 14:29 (02:29 PM) 7/12/25 and Piplup was started 14:29 (02:29 PM) 6/12/25, and since we cant see the seconds the bids were placed i believe Ynosvt's bid was placed within the allotted time for the auction of 24 hours and is therefore the winner with the highest bid.
Sorry, need to revise, Laviter is the winner since auction ended 14:29 and according to auction rules "If the auction ends at 15:00:00, bids are valid until 14:59:59 and no later.". Sorry for the misunderstanding.
