Sorry for asking this question again, but maybe my last message fell through the cracks.
The bug (that jumbled up the questions when editing them) is fixed.
I managed to reconstruct the order of the quizz that most students filled in.
I hit "regrade".
The grades look about right (I remember many of them).
However, the last of the 19 possible answers shows up as a blank in the students attempts (there were always 19 questions, I have not added a new one). As a result that question is not taken into account in the final grade, which can then be off by 1 point if the student checked the question (since that question is incorrect and should count as -1 or -10%)
In my message at the end of the thread called "regrading messes up grades" I attached a PDF where you can see the blank response. Unfortunately I had to truncate the PDF so you can't see how the final grade is wrong (should be 2 instead of 3).
Thanks for your help.
Ileana
One option appears as blank after re-editing the quizz (was old bug in Moodle 7.2.1 when editing questions)
