Pixel-Fed brings every week a content update. If you can't open the app after an update, try to uninstall and then reinstall the app. Nothing will be lost. If it doesn't work you have to raise a support ticket at http://support.pixelfederation.com/ts/?player_id=xxxxxxxx the player-ids of your sons.

Or you can search the offical TS-Forum https://forum.trainstationgame.com/index.php

Here on the Wiki we can't do anything for you, since we have nothing to do with the work of Pixel-Federation. We gather only the information about this game
