@StuartH it may have to do with how often NodeBB calls the filter:footer.build hook, and since it's a SINGLE PAGE APP, it's not much, I've seen that weirdness, but I am not too sure what to do about it, the filter is pretty straight forward. what you can do to verify that's the footer code is being generated correctly, is to view-source of the page, then search for nodebb-plugin-42 comment.
if for some reason, the javascript generated is invalid, you may have a page error. I am working on a fix for this issue
