When I refresh your website, although the state remains the same, but the page reloads to member-undefined.
The STATE remains the same —> RIGHT (aktive Question will remain the same) The same question will be loaded at the page.
- User-A enter the page, what does he see? Of course the last activated question, because when this page loads (a database-query starts and looks for the last activated question.) last activated question found? Yes! And load it onto the stage, to show this last activated question to all the USER who enters the page.
Why all USER?
Because everytime when a user enters the QUESTIONPAGE, a query-funktion starts, fired by onReady-command.
So what do EVERY USER see, when he enters the page?
YES, the last activated QUESTION.
That is how i would solve this issue. 
EDIT:
You have just to expand and modify the given CODE a llittle bit.
