The stats were reset but nothing has been lost. There was a "bug?" in the way the game was processing matches. This is being worked on now. The stats were reset so all the games played so far (several hundred thousand) can be reprocessed. Its fine to keep playing the backlog of game will eventually be processed and the records should all be acurate. This is the message that was posted into the gamespy mkd MOTD: "Mortal Kombat Deception has attracted a huge following of online gamers in just 10 short days. Because of the enormous quantity of games played, we in the process of reworking the game data so stats are accurately reflected. Feel free to continue playing online while this is being done, since no game stats will be lost during this period. Thanks for your patience...the Mortal Kombat team."
