I don't recall the "fetch from server" function to be a depreciated feature with the release of 1.2.64 and I maybe wrong. Try performing the function to see if it works.
Select from the menu 'File', then 'Preferences', then 'Node Subtypes'.
Select 'Restore Defaults', then 'OK', then 'Apply'.
Select 'Fetch from Server', then 'OK'.
Select 'OK' to finish.
Do these steps anytime new sub-types are added to your VIRL host.
