Xbox 360 rollback after bugged price

Last night some people noticed shares of Microsoft's Xbox 360 dropped to below 400 DKP. This was not the result of coordinated selling but some error that occurred during the period our web hosting tried moving the simExchange's database to another database server (which resulted in an inability for many users to connect for a few hours). All players making trades at the bugged price had their Xbox 360 transactions rolled back (you basically got a full refund).
