Description of your issue, suggested solution and other information

currently, downloading incorrect videos from facebook. as of yesterday, a recent (january) version of ytd downloaded the correct video but failed to extract the video name. so i updated to current, and now ytd is downloading the incorrect video (though it now handles the video name again - the one which matches the incorrect video).
