Aug 15 Challenge problem rejudge?

I’m wondering whether the challenge problem SCLUSTER from the Aug long challenge has been rejudged.
I don’t remember the exact scores,but the score of the best was slightly above 100 million during the contest(I mean the absolute score computed from the test files, not the relative score wrt. the best) . If I have understood the scoring mechanism correctly only one fifth of the testcases entered in the preliminary score. So the absolute score after rejudge should be around 500 million. But it has still the old value.

Did the rejudge actually take place?
