[2020] No buildings

Do you have a Forge Bowl event building in your City or Inventory? If so this may be related to"Loop Between Browser and App" issue.  

The developers are working on getting the app updated for the event and it does seem to be taking longer than normal. I will let you all know as soon as I hear something definitive. Thank you for your patience.  

If you are playing on Mobile, the latest version of the app is 1.192 dated 26 Nov (Android)/30 Nov(iOS).
If you have an earlier version an update is highly recommended.
