As an instructor, Create a quiz which uses a qtype_ddimageortext question having at least 3 choices and has several more questions. Set the time limit of the quiz to 1 minute to get attempts expired quickly. Also set the new page setting to "every question" to ensure the attempt will have multiple pages. As a student, attempt the quiz solving the 3 choice qtype_ddimageortext question but not finishing the attempt, for example, if the other questions are in another page, just change the page, and close the window. As an instructor, modify the quiz question by removing 1 of the choices Wait until the quiz expires (1 minute of wait should be enough).

The output should not show an error when finishing the unfinished attempts, this can be confirmed if  Considered X attempts in Y quizzes. appears.
