Comment (by Vladimiroff):
@akaariai, you're right. I was building the field_names wrong. The issue
was not only that `base_ptr_id` was with the wrong value, but *all* of the
values was getting mapped to the wrong field.
The only solution that I found was completely rebuilding the whole list
from scratch. Was that a good idea?
