      NOTE where I say '^M' you must insert a carriage return character into the field, on my OS this is achieved when I type ctrl-m

      1/ Create a new quiz with default settings
      2/ Add a multiple choice question to the quiz

      • Question Name: 'Duplication Problems'

      When attempting to duplicate a quiz using the x2 button the duplication fails. I thought this might be MDL-29432, but it doesn't seem to match any of the rules in that bug.

      When I attempt to replicate the issue on my local machine by backing up and restoring the whole course this works fine and I can't replicate the issue. I have access to the live data which might be useful to replicate and fix this issue.
