No threads found

Is this due to some changes going on? I keep getting this repeatedly, even when refreshing a page I'm already on, so I know it exists. I'm getting that result about 60% of the time for all categories and forum areas.
 
Solution
The "no threads" issue is known and being worked on.
To my knowledge it may have something to do with Amazon updating their servers (Tom's is hosted by them) recently, but cant say with any certainty whats causing it.
No. This just started today and I mean I can be looking at my own tracked threads page, hit refresh, and then suddenly it says "no threads found." By about the third refresh, it comes back. Same for individual categories as well. It's not any particular page, page number, category, or filter.
