4.16 Exponential Height Fog breaks building lighting

Hi!
Just installed 4.16 and wanted to try the new Volumetric Fog. But every time I place an Exponential Height Fog object in a level, no matter if it has default values or some stuff changed, my lighting crashes at 6% (I get the Lighting Error).
I have not fully tested every possible variable yet but every time I remove the Exponential Height Fog the lighting builds just fine.

Hi, can you give us the specific error message?

It just says Light Error, nothing else

How many fog actors do you have in the scene?
