Links in this page (topic list) are broken

Hi,

When clicking on a topic title in this page (https://feedback.photoshop.com/photoshop_family/categories/photoshop_family_photoshop_lightroom?topi...), I'm getting the following message :

Page not found :(
If you're looking for a product or company, confirm that the community domain you entered is correct in the URL. If you think you arrived at this page in error and found a bug, please report it in the Get Satisfaction customer community.

However reporting to Get Satisfaction is not possible, because you need to be a Get Satisfaction customer to do so.

Not all topic titles are affected, though. For example, the problem occurs with this link :

https://feedback.photoshop.com/photoshop_family/topics/lr-classic-dd-8-3-video-export-in-original-fo...

and several others but the links for other topics is valid.
