YouTube Import Issues (YoutubeParseException)

[HDFlood]

Having a bit of difficulties loading YouTube imports into SLAM. I've had this issue only recently. The consistent error seems to be YoutubeExtractor.YoutubeParseException. Examples:

--------------------18/11/2018 06:18:44 UTC--------------------
YoutubeExtractor.YoutubeParseException: Could not parse the Youtube page for URL http://youtube.com/watch?v=VnWEMCvlHck
This may be due to a change of the Youtube page structure.
Please report this bug at www.github.com/flagbug/YoutubeExtractor/issues ---> System.NotSupportedException: Result cannot be called on a failed Match.
   at System.Text.RegularExpressions.Match.Result(String replacement)
   at YoutubeExtractor.DownloadUrlResolver.GetHtml5PlayerVersion(JObject json)
   at YoutubeExtractor.DownloadUrlResolver.GetDownloadUrls(String videoUrl, Boolean decryptSignature)
   --- End of inner exception stack trace ---
   at YoutubeExtractor.DownloadUrlResolver.ThrowYoutubeParseException(Exception innerException, String videoUrl)
   at YoutubeExtractor.DownloadUrlResolver.GetDownloadUrls(String videoUrl, Boolean decryptSignature)

Like I said, I've only started getting this issue recently. Any feedback, help and/or redirects would be greatly appreciated.
