@nicksergeant When you change the options for a sorl thumbnail, the file name it generates will be different, and it will point to a non existing file, making the new thumbs 404.

The solution for this is regenerate all thumbnails every time this happens. We have a management command for this:
python manage.py fix_thumbnails --settings=unisubs_settings
That needs to be run on prod when the image settings change. I've just done this on prod, so it's more of a heads up for future needs.
