Changing the theme's path does not clear the cache

[einkoro]

Renaming the theme directory and then attempting to clear the cache does not seem to change the minified CSS as the hashes and filename are still the same. ie:
wp-content/themes/old-theme-name/ -> wp-content/themes/new-theme-name/

The only way I could get minqueue to produce a new minified file was to change a line of style.css itself.
