You guys have no idea how odd it is to see an entry like this in my Notifications feed...

@Vgrace573 - When you establish a new TS3 user game folder in Documents, there would be no added content at all. Thus no InstalledWorlds. The point of a clean folder like that is either to establish some sort of baseline through "vanilla" gameplay (no mods, store content, CC, extra worlds, game saves) or to begin fresh by reinstalling all or only what one needs.
There would be no WorldCache files if no worlds have been played yet. Not all worlds cache this way regardless, the base game, EP worlds and I think Riverview are designed to cache to a location within Program Files that isn't supposed to be touched.
Mixed Orign/disc installs that are managed by Origin and on Patch 1.69 will have their installed EPs show up some under Orign Games and some under EA Games, but basically wherever Origin thinks they should go. "Pulling" EP folders out would break the game install entirely, that's not a good way to uninstall an EP or any program that some other force is managing.
