We did update the app last month, and things do look a bit different. We've made the move to web-based charts, so your stats and friends' stats may not update immediately like before; however, the change should allow us to improve the app experience much more flexibly, which is a good thing.
Your info should all be there, though, so try signing out of the app and then back in again -- MyLand should reappear with all progress intact. Let me know how it goes!
Glad to hear it! You are very welcome!
