So, isn't in another bug in this case that you allow to bid a player? I expect in this case message "auction has end" and the bid would be invalid.
He saw in his screen starting price $ 7 000 000 and deadline 25/09/2011 14:11:46,
but was bidding player with starting price ? (something up to $ 7 000 000) and deadline 28/09/2011 14:12:10
