I lost my progress after an update. What should I do?

🤦‍♂️ Oh dear. Unfortunately sometimes this can happen, especially after a major update. We know how annoying this can be and do our best to ensure it doesn't happen. Unfortunately, the game data structures that underpin your saved games are so complex that, when we change things by adding new features or content, the saved game sometimes needs to wipe itself out to get a clean start. We apologize for the inevitable frustration associated with this and thank you for bearing with us as we work to add new content.
