Yes, I hate the site. Good riddance. Joking!
No, nothing's wrong with the website. There's been some changes that have been taking a while to do and even when there's some errors, no one ever notifies me or works it out. When I designed that infobox, I didn't have an Engines category and it was instead known as "Battery-Operated" which is a misleading category which I'm trying to get rid of when over 200 articles use it. I don't really expect people to click on things, but it's now fixed and it links to the category. Thanks.
