Hi, haven't applied the patch yet but the issue is activated by adding more than one question of the same type in the one quiz. Have tried all combinations of question type and its the same for all. Ive reordered the questions but as soon as the second instance of the question type is loaded the error 'Fatal error: Nesting level too deep - recursive dependency? in /code/web/modules/quiz/src/Entity/QuizResultAnswer.php on line 146'. Will try patch and see what happens.
