I don't know when it happened or how, but at some point everything in my Junkbox was duplicated, dozens of times for the playlists/folders (including the content) and 100s of times for the tracks outside the playlists. I know I didn't do anything to cause this as I've not bene working creating games or editing existing ones in a number of months. Deleting the folders wasn't horrible, but right clicking each track and selecting delete 100s of times was tedious. I ended up deleting all the tracks and folders becasue trying to sort it out wasn't going to be feasible. Just letting you know in case it might have been something recent.
