UnrealLightmass stops unexpectedly
I have a map in which I'm trying to build lighting, however UnrealLightmass stops unexpectedly without any reason (and with any quality). This is the first time it ever happen in my case.
According to the generated minidump :
To avoid issues with privacy I would like to send my crash dump privately to an UE support guy or developer in case it would help.

I debugged a lightmass crash in 4.16 last night which could cause the logs you have entered. In our case the data in the Swarm Cache was stale caused the LOD data to be very incorrect. Cleaning out the SwarmCache folder fixes the issue as a work around. I'm not sure how we managed to get our cached data into that state but this could alleviate the crashes you experience
