Blocker Description
When a teacher (with normal user rights, not admin) makes a backup of his course and when he tries to restore the zip-file on the same or different server (deleting the newly created course area first before adding data to it), quiz results are not restored correctly. The main problem: when a teacher goes to any of the restored course areas's quizzes and looks at the "show all attempts" page, the teacher is able to see the quiz scores for each student but when the teacher clicks the individual attempt's score (in order to see the student's question sheet), moodle gives the following error:
"This question has been deleted. Please contact your teacher"
Here's the working and non-working course areas html source codes:

When I look at our production db (=postgres), I can find the question (id=8315) in the db but when I look at our test server's db (=postgres too) and the restored course area's question with the id=8330, I get nothing:
=> select name from mdl_question where id ='8330';
name
------
(0 rows)
When I look at the course backup file (the zip) and the xml inside it, I can see the question with the id=8330 correctly there. Here's a sample of what's in the xml:

To me it seems that the restore feature does something really wrong. In fact, we were forced to go back to our backups and restore the whole production server's db to the state prior to the user-made course restore -episode because the user-made restore didn't only restore the course area unsuccessfully but it also:
1) destroyed the quiz results data (same error message: "This question has been deleted. Please contact your teacher") in OTHER course areas!
2) altered quizzes in OTHER course areas (in our production site) so that the quizzes no longer had questions inside them and the question scores disappeared.
I had to comment out the restore function from the <site-url>/files/files.php for now. The problem seems to persist since I can reproduce it in our test server with the same problematic results.
Help truly appreciated!!!
