Do Groups in Node editor cause problems in Verge?

I just recently took a very complex node system that works just fine normally..
and organized it all to tighten it up to be more understandable..
i grouped 3 of the areas of nodes into their own groups.
now the item wont even show up in verge, though it does fine in the blender view port and render.

are there any issues using multiple groups that you’re aware of?
i have some materials that have just ONE group in them and that works fine.

thanks!
