Lightmass crash

I made a fresh 4.18 build and project, added a Lightmass Importance Volume to it and hit build.

Lightmass crashes with this swarm agent log:

Its trying to allocate 18446744070209521004 bytes, thats 18446744 terabytes, that cant be right…
Any ideas?

Also getting errors.
Its not in the same place every time either, i think i got to 80-something % yesterday, but, mainly gets to 30-something % and i get this.

EDIT:
Fixed my issue, i found a random “foliage” that was at 0,0,0 for some random reason and deleted it. Lighting seems to be building for the time being. It took me about an hour to get to 99%. This 1% is taking over 5 hours and its still scrolling across… not sure if this is supposed to happen, or … not.
