I’m working on a project, I’m on 5.4 version and I’m using baked lighting; swarm agent no GPU Lightmass.  
The light building process gets stuck at 0% for a looooooooooooooong time then starts very slowly.  
I have kept all the lightmass resolutions at green, and this happens at the preview level.

Have in mind this happened overnight. one night everything is going well, the next day I run into this issue while nothing has changed.
