First, I noticed I was unable to visit the "Not categorized" category. Every time I tried, it said it didn't exist or was private.
Then, when I got to create this topic, I noticed something odd: I couldn't change the category of a Topic I was making. I could when I actually went to a category page, but then it's just stuck on that category. It only shows one category at a time. So, yeah, could someone move this to Site Bugs for me? As explained, I cannot create a topic there. I am only able to create one for the Off-topic category.
