I would like to thank Morlag of Landroval for alerting me to the fact that more than 50% of Episode 20 had failed to upload (which explains why it only took 3 minutes to upload . . .). After being alerted to the issue I was able to find that the error was in the base MP3 file and that my editing software was not properly creating the MP3, cutting it off at about 16:48. After numerous failed attempts to fix this I went online and downloaded a new version of my editor, dumped the old one and that has solved the problem. The new version is up now so be sure to clear the faulty one and re-download the full version of Episode 20.
