so, removing the highlight file resolved it. Is there any way to get that back? I do have it in Dropbox. However, is that file now corrupted? I would like to be able to retain that file if possible. However, it's not a huge file, and I've only recently begun using highlights regularly, so if I lose it, then so be it. Is there any way to not corrupt the files? Am I doing something wrong, or is this a bug that is being addressed?
