The Farmhouse will be updated in the near future, but until then there will be some preparation changes that will happen this Friday, 19th of October:

• The town crier will be disabled. There will be a button instead, with a tooltip that informs the users that something new is being worked on.
• The Extra farm challenges and the extra Bahamarama challenges will be removed from the Shopping Center.

Please prepare your Farmhouse challenges accordingly.
