Thanks Chaitanya, This sent me on the right path. I had implemented a custom remove on the children and was calling the MOC -deleteObject method to remove a child from MOC.
The docs say this on the deletedObjects method: Discussion Note that the returned set does not necessarily include all the objects that have been deleted (using deleteObject:)—if an object has been inserted and deleted without an intervening save operation, it is not included in the set. I was able to remove and clean up some legacy code, thanks so much!
