To test this Create a new quiz. Add headings and question ( https://docs.moodle.org/35/en/Building_Quiz ) to make this structure Heading 1 Page 1 Question 1 Question 2 Heading 2 Page 2 Question 3 Now, drag Question 2 towards the bottom and drop it between Heading 2 and Page 2 (like in the attachment "Triggers bug.png"). When you release the mouse, the question will immediately move to after Page 2 (this is correct). Once the page has finished updating (progress twirly thing goes away), press F5 to reload the whole page. When the page reloads nothing should move. (Before this fix, sometimes, Q2 would move back to Page 1. That was the bug.) If necessary, move Q2 back to where it started, and then press F5 so you are ready to test again. This bug depended on exactly where Q2 was dropped, so repeat steps 3-6 above, dropping Q2 in a variety of different places, to make sure this bug is fixed in all cases.
