Topic missing from board but not deleted

I posted a new topic with some feedback to the new client, and someone replied to it. But I was, and still am, unable to navigate through the board to actually find my topic again. It's like it belongs to the board "Client Discussion" but is hidden somehow. Can anyone tell what's going on?

Here's a direct link to the relevant topic: http://boards.na.leagueoflegends.com/en/c/alpha-client-discussion/nqrqj607-new-client-feedback
