Unable to update rating changes

The rating changes after contests are not reflected in `;handle list`. I have tried all four sub-functions in the `;cache` category but none seemed to work.

Start by reproducing the rating-change issue with `;handle list` after a contest, then inspect the four sub-functions in the `;cache` category mentioned in the report. Confirm which cache path supplies ratings and verify that updated ratings appear in `;handle list` after the fix.
