Snapshot not saving to Google Drive

So I am going merrily along thinking my backups are being saved to Google Drive. Now, having a problem setting up another site to use your Managed Backup I go back and check the 2 sites I supposedly have set up to save to Google Drive, and lo and behold, there are no backups on my Drive since June! This is on 2 sites on different servers. When I go into the Destination in Snapshot it says it is complete (and backups were saved up until June), but there is the following error at the bottom: Fatal error: Call to a member function log_message() on null in /home/site/public_html/wp-content/plugins/snapshot/lib/Snapshot/Model/Destination/google-drive/index.php on line 259

I have authorized support access on both sites if it is helpful for you to log in.
