New data:

If the question is edited and saved without changing the wording of the question has the same problem.

When the question is saved, modified or not, reference to the response mdl_question_answers change

Could you look if the subquestions id were changed.
These can be found in the mdl_questions where the parent is the main question id.
The main question contain the text and the sub contain the {....} code

Cannot reproduce on a MYSQL database 1.9 BUILD (20090427).
There was not so many changes from 20090128.
As you have access to mdl_question_answers data, take a look on mdl_questions if the subquestions id were also changed.
Did you move the questions from one category to a another one after creating them?

To trace the problem in the tables:

mdl_quiz -> are the questions -> does not change
mdl_question -> multianswers type -> no change
mdl_question_multianswer -> sequence of option -> Change, new sequence
mdl_question -> text of Cloze response (Sequence) -> Changes, delete the previous references and creating new reference.
mdl_question_answers -> answer -> Change, delete the previous references and creating new reference

-----------------------
Student response
mdl_question_states -> answers answered by students -> no change id kept the old Tabal mdl_question_answers

In version 1.9.4 + is not the problem.

Your comment that there are not many changes, know what?

mdl_question_multianswer -> sequence of option -> Change, new sequence
This is what I suspect, new subquestions are generated, the old ones are not reused.
this is probaly related to the code around line 80
// First we get all the existing wrapped questions
if (!$oldwrappedids = get_field('question_multianswer', 'sequence', 'question', $question->id)) { $oldwrappedquestions = array(); } else { $oldwrappedquestions = get_records_list('question', 'id', $oldwrappedids, 'id ASC'); }
$sequence = array();
foreach($question->options->questions as $wrapped) {
if (!empty($wrapped)){
// if we still have some old wrapped question ids, reuse the next of them

if (is_array($oldwrappedquestions) && $oldwrappedquestion = array_shift($oldwrappedquestions)) {
$wrapped->id = $oldwrappedquestion->id;
so the best thing is to migrate to a new 1.9 version as this problem is solved in later versions.
You can test on my installation at
http://132.208.141.198/moodle_19/mod
log as user:moodle pw:moodle
If you look at the mdl_question table,
locate the main question which as an id given by the or preview edit link like
http://132.208.141.198/moodle_19/question/question.php?id=1484
then locat the subquestions which are questions with the parent set to the main question id (here 1484)
they should be in succession and should not change if you just edit the cloze question the way you do it.
They could change if you add or displace the subuestions order.
