Crash Bug with Progressive & old Render Region

Not sure if this is much of an issue, but I just managed to crash MAX:

1. Open old scene (pre VRay 3.3) with active render region
2. Change render size, so the region is out of bounds.
3. Set Progressive Image Sampler
4. Hit Render → Crash

No Crash with Adaptive Sampler, no crash when the region is disabled or a new region is defined.

Stripped down scene:
vray_progressive_region_debug.zip (2.82 MB)

Thanks for the feedback, instructions and scene.
I managed to reproduce the crash and will make a note about it into our system.

The issue has been fixed for the next service pack.
Thank you very much for the feedback again.
