Unity crash after clicking "Generate Global Scene Light Probes"

[oprincipe]

All the world is almost set up.

After few changes I wish to generate the global scene light (4 terrains scenes actually) but, as soon as I click, unity just crash and

I have to reload the editor again.

Is there any suggestion or a way to fix it?

Thanks

Light Probes are handled through Unity, while we have them in our inspector, that is just for quick access. 
If the light probes are crashing your project that would be a Unity issue and not a whole lot we can actually do about it. 
You could try to reduce the light probes per row / column and see if that helps. 

Start small and build up to see maybe its a memory issue is why its crashing. 
Otherwise the only advice I could give you would to be contact Unity support on this issue.
