32		Each time `ref.obj` is accessed, a new instance is created for its value. This is a problem, since doing something like `ref.obj.field = 1; ref.obj.save()` won't actually update the field in the database. This only happens when the referenced object is an instance of a model that subclasses another model. (So, it wouldn't happen if referencing `OtherSuper` in the models above.)

The `refresh_from_db()` call is also necessary to reproduce this in a simple test like the above; it happens with any instance created from an existing DB record.
