My new base is too dark (it has power and no holes)

SN1. Not sure what's going on. Game is literally unplayable like this.

After learning the ins and outs of base building and getting the schematics I needed, I decided to uproot and move to a new, larger location for my main base. So I know what the lighting is meant to be like. Fast forward to my new, larger base in a new location, but the lighting is half that of my original base and I have no idea what's wrong.

Yes it's powered, no it doesn't have any leaks. I built it on the outside in one go, of course at the time it had no power and was riddled with leaks. But I fixed all that and the base computer voice said "yep, all fixed, draining now". So I thoght, great! Only the base computer never fixed the lighting by bringing it back to regular luminosity.

After moving all my stuff and rebuilding, there's no way I'm gonna go through that process again if it's a bug. I'd rather just uninstall and call it a day.

Anyone know how to fix this?

Thanks!
