Crash in RenderBufferManager::ReleaseTempBuffer

I am running 5.4b14. I have had this crash since 5.4b11, possibly before. Is there a fix? I get this running in editor or a build. This occurs when running a nighttime version of my app. When I run in daytime, no crash. I have not isolated it yet. Nighttime just uses different lights, nothing special. I have disabled Graphics Jobs, Static and Dynamic batching and still get the crash. The app is VR.

thanks.

========== END OF STACKTRACE ===========

 

Seems to be related to having hard shadows on a flash light. Disabling the shadows restores stability so far. Maybe it's shadows casting horizontal to the ground. It's a trivial repro for me.

 

Bug report # please?
