I am running Moodle v3.0.3.
After students took a quiz, I realized there was a multiple choice question that was marked incorrectly because the answer listed was wrong. I changed to the correct answer and then clicked "Dry run a full regrade." Moodle then showed me the results in need of regrading. So then I clicked "Regrade attempts marked as needing regrading."
The file below shows the error.
I have encountered this error before. The workaround is the manually click the students that show they are in need of regrading instead of using the "Regrade attempts marked as needing regrading."
I am wondering if anyone else has encountered this error? Clicking the "more information" link yields nothing.
