The problem is that the way NSDocuments are used is semantically different from 
the way databases are used, and you *cannot* reconcile the two across all the 
functions on the NSDocument-based File menu. (This was an old discussion.)

You are probably falling foul of Sudden Termination:

You can try opting out of this completely, or opting out temporarily. Or 
possibly the change count type I suggested doesn’t cause the opt-out behavior 
in NSDocument, in which case you could try NSDocumentChangeDone instead. Or 
possibly the change count has to be updated later.
