I'm rebuilding a site that had the Spider Video Player plugin installed, but it won't be used in the new version of the site. Prior to starting development of the new site I imported the live db. It has many 'spider' tables within it. Is it safe for me to simply drop those tables? Or do I need to uninstall Spider from the live site, then re-import the db to Staging in order to safely remove those 'spider' tables.
