The software they use for this board is super buggy – it’ll produce things like that every once in a while, usually goes away after a day, or try clearing your browser cache, or try a different browser.
Sometimes it affects all users, sometimes just one. Looks like this one is just you.
Whenever I have a puzzling experience with a website on a Sunday, I assume/hope it’s because the TechnoWizards do maintenance on Sundays. It would be interesing to see if it’s better on Monday. This may just be something I made up, YMMV.
