1. Child ages should never be shared this way. By definition they are only sharable with neighbors. Period.
2. The pellet caves should not be shared by symbol. They have a different mechanism for sharing.
So this patch only hides what should never have been shared in the first place.
Now the books I am about to patch are a different story. Some can be fixed in the max files. But then you can always revert these changes once that is done.
Edit: And if you hadn't noticed, xLinkingBookGUIPopup is a big collection of special casing.
