SceneAssembly + VrayProxy

[image_pictures]

We have a problem with maya sceneAssembly.
when assembly load proxy representation, it give me some strange, unknown errors

When I open this scene with proxy separatly, this errors not appear.

In scene with 100 AssemblyReferences it became a problem, and produce very long time saving scene. (15 min, before saving status bar appear)
In 3.2 build we don't have this problems.

sorry for my english )

I was unable to reproduce the issue with your scene. I have 100 assembly representations in my scene, and neither switching through the representations nor saving the scene produces any noticeable slowdown.
Could you confirm that you are able to reproduce the issue with the scene you se
