We received lot of ss about the half page in the game.
Same problem on my account also.
For now, maybe that will help, all unframed options (on my account) are showing whole page.
(www.mafiawars.com, Lucifer's Happy Place or Spocks unframe option).
One more thing, it seems that at this moment if you try to enter the game either through bookmark of feed, game opens unframed. Can be that this is just case for some players only.
Zynga is unavailable on chat, e-mail is working for players that are having that option to contact Support.
