WR-06: a Question save hook clears grading_status on the answers of a question that changed type away from open, in the save's transaction, so they leave the review queue and needs_review. GradeAnswer ignores a question that is no longer open, and a choice or self-check re-answer clears the text, grade and review columns of its row.
