Minified JS file won't regenerate

I accidentally placed a CSS script in the Minify JS Scripts box and hit save ( http://screencast.com/t/baC3Lo603Dt ). This appeared to generate a bad JS file with both JS and CSS mixed. http://screencast.com/t/DEoUkhkf

Once I realized the problem, removed the CSS reference, and emptied all caches (we have no CDN turned on), the bad JS file persisted with the same name.

Nothing I do, even manually deleting the minify folder contents from the server seems to kill off this bad file. For what it might be worth, these are the scripts and css I’m minifying: http://screencast.com/t/Hkl94ghkAYH

Thanks for any advice.
