The subclasses of that class only inherit it, they don't have their own copies of that information. So when you delete the property/method from the class the subclasses just lose it. And you might not notice it because VFP would just create a private memvar for the missing property if the subclass overrode the value. It would error out though the first time you tried to access/set this.TheDeletedProperty.

Thanks, David. I hadn't noticed that there were reserved memo field entries for those properties. And you're correct, there is no error until you actually try to access the deleted property in a method.
