I experienced the following strange and frustrating issue with quiz today and need to make absolutely sure it does not recur: I ran an examination with 82 students today, during which 6 testakers believeably complained that Moodle had "forgotten" essay answers when they tried to navigate back and take another look. The examination is broken down into two quizzes that the students have to take sequentially for administrative reasons.
The quiz in question contained a mix of MC, Cloze and Essay questions, the critical one was on a separate page with a longer writing prompt. I neither experienced the Problem with older versions of Moodle nor, until today, with a recent one. I would be extremely grateful for any input/suggestions where to look to rule this out for the future. Something ugly must be going on, but where?
Thanks & regards,
