I haven't used mafia at all since a few days before NS13, and I see no difference in what I'm experiencing now that I did five days ago. Unless those daily builds have the new areas and content in them already, having the builds up or not isn't going to make a bit of difference to whatever lag people may be experiencing.
People have waited a long time for NS13 to roll out, some have been bored and didn't play as much, the new content has them trying to see as much of it as they possibly can, drinking it all in, trying to figure it all out, and in my case spending even more time trying to figure things out because the quests aren't as straight forward as they have been in the past.
As for the comments for others asking for something to be released they can use to alleviate some of the cocktail crafting, cooking, display case, pain in the tush operations; if that's all you're going to be doing, I suggest that you use an older one. Log in, do it up fast, log out and open your browser for adventuring. For the new items to use and make things with and adventuring, go into a browser and figure them out. This stuff shouldn't be missed by adventuring automatically, you've waited a long time for it, its here, savor the fun of it, the complexity, the skill that went into just an amazing addition to the game.
