VRay2 - Environment Fog crash

I have a scene with a few geometry vol fog gizmos which renders fine.
When I click merge in the Environment tab and select the same scene to duplicate my EnvFog effect it seems to merge fine - although no gizmos is now attached to that effect. When I select the merged effect and click Add under the Gizmo tab max crashes.

Edit:

It seems a bit random now when I remove and add gizmos which ones will be active when rendered.

Scene:
dense_nebula_02.zip

Vray EnvFog really crashes.

1) I made a simple scene. I think falloff radius didnt work (only new falloff per gizmo)
2) In this scene, make one environmental fog in one gizmo, then make another envfog and apply another object as a gizmo. But when I switch to the first envfog, it has the second object as a gizmo. I think its a bug, becose its render ok in both gizmos, but in the menu objects is wrong in the list and when I wanna change these objects, remove or add, vray crash.

Anyone else experiencing these problems - or are they already fixed for the next beta?

Thanks for reporting the issues; will check these out.

Best regards,
Vlado

Meanwhile I may have another issue.

This scene has a vray light and GI enabled IR+LC:


First image with fog emission value 1,1,1.


Second image with fog emission value 0,0,0 (I only updated the region).

Is it really supposed to spike off that much of a difference?
