I still have no idea what's caused it, but I'm certain there's something in the formatting, or maybe uploading those images that caused PeakD's editor to freak out. I'm sure this is a pretty rare occurrence, since it works beautifully most of the time. In any case, my post is published now, and I had to use Hive.Blog's editor instead to get around the issue. 🙃
