A required update was released for Madden 08 on the Xbox 360. The PS3 will receive this same patch soon.
The details on what this update corrected follows below:
Franchise: Editing a player causes his contract value to change
Franchise: Former user coaches do not fill their new team’s roster causing the game to stop simulating.
Franchise: The game crashes when simulating if the user releases all the HOF players from the Player Management Menu and then starts a franchise
Train for This Game: Certain Player Weapons Stat Points are not being recorded after Training.
Online: In Game: If the Client pulls connection at the end of game, prior to the Match Up screen, they will crash the Host.
Online: When the client ejects disk after the game clock has been reduced to 0:00 but before the opponent gets the match-up screen the Host will crash.
This update is not representative of a potentially more complete patch that will address gameplay and other franchise issues.
