Since this affects especially BBLog I post this here, too.
Starting tomorrow 2012-06-12 we will move our history database.
This means, that all your new history entries will be written to a new database.
Your old history entries will not be visible until the maintenance for your platform(pc,ps3,360) is finished.
Because we are moving those old entries in the background.
It's almost 400GB of database data, which could take some hours to export, transfer, import.
