Url problem in community answers

Hello Mavrick,

Hope you can help me with this one. I have my community answers working and installed fine. At the moment
the url would read something like mysite.com.au/qa/view/292-my-answer-to-my-qustions.

But I noticed that after the /qa/ If i type any url that doesnt exist would redirect back to the questions and answers home page.

For example I could type any of these links below:

mysite.com.au/qa/view/292-my-answer-to-my-spellingmistae
mysite.com.au/qa/whateveriwant
mysite.com.au/qa/wrongurl
mysite.com.au/qa/dasdasdjhasjdhjadowdqwoid

They would all redirect back to

mysite.com.au/qa/.

Why is this? The problem is that it's causing massive amounts of duplicate content on Google. :(
