I have an issue where when a user clicks on the newly added "Submit different answer" link the page refreshes and the body of the page is blank. The header and footer show up but nothing else.
I was able to find that the when you click that link it was filtering out a character in the URL. (?)
I have attached a before and after of the URL.
I have since removed the character so things work, but wanted to make sure you were aware this.
