Hi, I'm having problems with inserting the Answer Feedback to Long Answer Questions (Tested on Opigno 1.20 and 1.21). Giving the grades for Long Answer Questions works fine but giving the feedback while setting the grade is not working. After you submitting the grade shows as intented but the feedback field is empty (occurs on both admin and student side). I believe it is related to this issue: https://www.drupal.org/node/2380523, but I was unable to make this patch work with Long Answer Question. Do you have any quick fix for this or plans to upgrade the Quiz to the newer version 7.x-5.x, where this issue should be already fixed?
