Crab, let me run this possibility by you, and see what you think.
Initial approach on Westerly heading was an attempt to get in visually. Finals checklist includes item "Radar-stby".
This approach - lost visual, go around. Go around checklist does not include include item "radar-on". Second, ARA-style approach conducted with radar at stby, and SA is lost as a result.
I have seen similar in OGP sim training.
