Quiz timer

I see that this post is two years old, however, I hope the wheels are still in motion to look into it unless it has been fixed in version 2.

I'm using SL1 and I encountered a rare event when the quiz timer expires on the last question answered correctly.  

In my quiz, the passing score is 100%, the Review Quiz option is not checked, the user can retry, and the quiz timer is set for two minutes. 

After answering all questions correctly, I clicked the Submit button on the last question at 1:59. I got both the Correct feedback and the time expired alert.

When I clicked the OK button on the alert, it took me to the start of the quiz but it showed the completed question, and clicking the submit button had no effect. There were no other navigation options. I was stuck.

I have tried to reproduce this, but it only happened once.
