it's the onlt bug i found since launch.
EVERY SETTLEMENT EXCEPT SANCTUARY HILLS have the basic light bugged.
it just doesn't work even with energy.
industrial light, ventilator and etc works just fine.
bug the basic, and most important light source doesn't.
it's horrible building a settlement and not having decent light.
fix it please, because you can't use mods in concoles as far as i know.
