Hi Sarah…. that is going to be a WP Google plugin issue to take up with the developer’s support because that is a bit concerning that it would delete a map. Updating the plugin won’t have anything to do with the theme, but if you want to revert back to a previous version of a plugin, click on the plugin page’s Developer tab at wordpress.org and you should be able to download a previous version. Bu I would still inform the developer what happened.
