Re: Foundations moves whole lot
@alicecharnley I just realized that you are on the 'Old Salt House" and what the issue is. As I mentioned in the other comment this is a situation where the builder did create the entire area in a way where the game sees it all as connected since there is no yard (no real grass other than perhaps 'grass tile', which is different than the 'real grass').
Please see this video to see how to disconnect the fencing from the house: https://youtu.be/IBFvmBlZicY
