Smushed dev site, then moved site. Smush stuck

Hi is the live site, and is my development site. I started a bulk smush on the dev site ( but it was estimated to be 12 days so I didn't wait and duplicated the dev site to the liver URL. Now the smush has finished, and the dev site was able to download the smushed files, but the live site cannot. The live site says "Woohooo, we are crunching the numbers for you and than it is all done."

Could you please tell me how to correct this problem? I can manually FTP the smushed files from the dev site to the live site, I just want to be able to smush stuff from the live site in future.
