Some users of Artifice have reported a crash when trying to play against the device AI. I found the cause of this crash and it will be fixed with the next release. I will be submitting a new version to the App Store this weekend. In the meantime there is a workaround. When you go to the choose opponent screen wait till your list of friends is done loading before selecting Device AI. When the list is done loading you should be able to select device AI without a crash. Thanks for your patience and sorry for any inconvenience.
