What were OLYMRANK incorrect test cases?

general

In the contest page, there was an announcement that OLYMRANK would be non-scorable due to “incorrect test cases”.

Problem OLYMRANK is being made non scorable since two test files #8 and #11 were found to be incorrect. Since the issue was found late into the contest, the problem is being made non-scorable.
We apologize for the inconvenience caused. The corrected version will be added to the practice section in a couple of days.

What does this mean, exactly? I (and other people) were able to submit and get AC.

  1. Will there be a more detailed explanation?
  2. Does this mean my solution was wrong?
  3. Is the current version in the practice section updated with corrected test cases, or is it still incorrect?
  4. Will there be an editorial published?
