Episode Thumbs

Hello,

I have noticed that when scraping my Kodi Library for a new TV Show that is using TMM nfo files, the episode thumbs do not get scraped. I am forced to call up the info screen in Kodi and add the artwork manually. Bit of a pain when the show has 66 episodes and they all need to be manually added.

Is this a known issue? Any idea how to resolve this?

Thanks
