Resuming multi-choice random question not working

Hi,

I have used quiz module for one of my project and found one issue in resuming random questions.

Please find the steps to replicate the issue
1. Create "Categorized random questions" quiz with "Taking option :Allow Resume" with 7 multichoice questions.
2. Configure to show only 5 multichoice questions.
3. Take quiz. Attend only 3 questions and then logout
4. Then login and resume the quiz. It should actually resume from 4th question but it is resuming from 3rd question again.

Please check this.
