I also have same problems which the file is missing.

To help everyone, I found a easy bug to fix. In SelectQuestionGroupViewController, you need create a link between tableView code with Main Storyboard.
The bug showed after you add a question group, the tableView is nil, and can’t reloadData.
It’s only a detail, the course is very good!
