Install "script.skin.helper.widgets" and/or "service.library.data.provider" to gain access to the widget you want again. Both are under 'Video add-ons' in the Kodi Repository.
Once either has been added, navigate to choosing a widget in the skin, and they should be within 'Default Widgets' in the list. Sounds like you used to use the Library Data Provider one, which is labelled 'Recommended Episodes'.
