the problem with that is we have no idea what further choices both the current seller and the current owner have made predicated on the sale as it went through, both the fact that it went through and how much was paid could have caused them to make other choices, like expanding the arena, or buying a second player, and now they wouldn't have the money to compete with your bidding, but if the bidding had been just extended at that time they would have had the funds available.. you see the sorts of problems that come up when you retroactively try to fix things?
i'm not trying to deny you were disadvantaged, just that fixing that disadvantage is not possible without disadvantaging someone else.
