I gave a quiz that had random-ordered questions, some of which were matching. One of the matching questions had two mistakes. After reading https://moodle.org/mod/forum/discuss.php?d=169249 I get the impression that if I fix the mistake in the question, then regrade, it will change the quiz results. However, there seems to be no effect.
I should point out, too, that the quiz allowed 3 attempts, of which the highest one is kept. I thought regrade would regrade all the attempts and recalculate the best ones. When I run regrade, it says everything was OK, but nothing changes.
I verified the question in the bank is indeed changed correctly.
Is there a way to automatically regrade after this kind of mistake?
Thanks in advance,
p.s. I just found this bug classified as Major from 2006: https://tracker.moodle.org/browse/MDL-5560 - seems related.
