We have had an issue for years that I cannot seem to get answers for. We have a large Moodle campus (1.9.11+) with several instances of a course. Whenever we make a change to an exam question (in the bank), the old question re-appears at a later date. We have gone as far as editing the question in the bank and then editing each and every instance of the exams that use this edited question, be they always manage to revert back to the original at a later date. Isn't there a universal way of editing exam questions that would propagate across all exams that use this edited question? So if a single student attemtps a quiz, the exam questions can no longer be edited for errors? The only remedy is to re-create the exams to pull in the new edited questions from the bank?
P.S. Using Moodle 1.9.11
