I tried to reproduce this problem in my app and couldn't. I got these types of exceptions in the past when I was using KVO with my managed objects, but I no longer do that. If you aren't either, then I don't have any other suggestions.
In my app, I have parent objects with many child objects that have component objects. The component objects are large and don't get faulted in when opening a document. There is a cascade delete rule from child to component. I deleted a child object and saved the document. Then I performed an undo operation, and the child and its component were both correctly brought back to life (I could edit both of them), even though the component had never been faulted in before the delete. So Core Data is saving their attributes somewhere other than the persistent store.
