Thanks for your feedback and making us aware of your feelings regarding the change to the rocks counting towards terrain requirements.
We completely agreed with your feedback as it, unintentionally, affected a lot of previous work; so we want to let you know it has been reverted back to what how it worked previously.
That is: rocks will no longer impact the terrain requirement for your animals. You are once again free to use however many rocks you would like!
This revert has not impacted Update 1.0.2.
Thank you for all of your support. You all rock! 💚:D
