VaAddSolids doesn't always work

Sometimes I have to save/close/open to make it work again.

Hi @djhg can you share a 3dm file where this happens?

I will upload it momentarily. It’s the same project as the issue with linked copies.

Got it! Could you point me out which VA objects and Rhino solids don’t join properly with the vaAddSolids command?
Keep in mind that Rhino solids must be closed polysurfaces or extrusions.

Yes, these ones were closed, but wouldn’t add.
It’s the same ones which were linked. Sometimes they would add, sometimes they wouldn’t.
