The issue here seems to have been that the structure of theme packages has changed and file paths got disconnected. In default.html I removed some out-of-date paths, and updated the structure of a theme package, both on the built in themes and external.
This meant moving all of the theme code into a subdirectory package and adding an empty style-override.css file. Will add to the docs what a minimum theme package should look like.
