Load the game with a wired controller (or connect your wireless controller with the play and charge kit). After getting to your garden, press X to bring up the menu wheel. Your game will continue to play as long as you do not go any deeper into the menus. This will prevent the challenge window to open randomly. Simply turn off the display and allow the game to idle. Note: The game will not autosave in this state. You may want to close the menu every so often to save, then open the menu up again.
