When using the phone version of the game and you are travelling...
When you try and return to torn, there are two buttons.
1. You must press and then from the drop down choose to return to torn
2. The Log out button.
if you don't have a big screen on your phone these two buttons are quite close and more often than you will end up logging out of the game rather than returning.
Suggestion:
Place a button at the end of the travel page on its own on the mobile version of the game to return to torn, without the risk of logging out.
