Just when we were starting to commit our Central Mainframe Access Code to memory, Mafia Wars says it's going to give this new bonus system an overhaul. That means there's good news and bad news. First, the good news -- codes can be accessed in game, and will no longer need to be written down. Then, the bad news: Right now you can redeem this code for a reward daily, but post-overhaul, rewards will be doled out weekly instead. Boo.
If you're one of the few who lost your code this week, this Mafia Wars forum post says not to contact support -- "They cannot assist Users with retrieving them at this point in time." Guess you'll have to sit tight until this Central Mainframe access is retooled later this week.
