Seems that bidding the same amount as the previous bidder wins at the maximum bid of 2.1 million.
player 1 bids 2.1 million and becomes high bidder.
player 2 bids 2.1 million: player 1 gets the 2.1 million bid back as "outbid" and player 2 is high bidder.
if nothing further happens player 2 gets the item.
Has it always been like that?
