I bet Alice was a developer too.
Have you overridden any of the EOF methods, or the generated methods in User or DataBlock and changed the normal behavior? Or forgotten to call super?

Aside of that, I have added a log into the DatabaseContextDelegate.databaseContextShouldUpdateCurrentSnapshot method, and here I *never* get *anything* for the relationships:
neither the old (which is presumable) *nor the new* dictionary ever contain the “userDataBlocks” or “dataBlockUsers” key — not once.
well this one's weird, or I am missing something of importance here.
Meantime, I have played with another M:N, which works without a glitch (and which is modelled the same way as that one which does not, incidentally). Here, save-time, the snapshot
does contain the proper related objects (and thus proper INSERTs are generated).
The weird thing is that these objects *do not* come into the snapshot through the DatabaseContextDelegate.databaseContextShouldUpdateCurrentSnapshot method! It logs all right
when the object is fetched, but the new (nor the old, of course) dictionary does *not* contain the relationship key at all -- precisely the same way it is with that relationship which does not work properly!
Nevertheless, as mentioned above, save-time, the snapshot is all right. Couriouser and couriouser, Alice would say :-O
