I actually landed on the Sitepoint article but followed the link here. I had used a similar query in the past and had this exact same thing happen to me. Several of my categories disappeared from a group of my links and I had no idea this was the cause. I've saved this bit of code and will be using it in the future instead. Thanks again!
