Game hints indicate further Zoe activity, but previous comments here indicate that there is none. I really enjoyed the updates for Elizabeth, Jessica, Nichole, and Sophie. And I did enjoy the Christmas hidden story.
To open the in-game console: (In windows) go to the top level folder for the game, then go into the renpy\common directory in there. Open up 00console.rpy and search for "config.console". Change it from "False" to "True". Then launch the game. To enter the in-game console press the [shift]O keys.
To fix the errors in this update type: "intro_nude_button = False" and hit enter, then esc back into the game.
