Lighting Not Updating Within Interiors

Daylight/Nightlight leaks through into builds where there should be none.

I have provided screenshots below that feature a build of mine, where each section is entirely encased within a black concrete box.

There is no possible way for light to be leaking into the build, yet it does.

The lighting issue will come and go, sometimes it’s very obvious, and sometimes it’s only patchy, and it will vary every time you reload the world.

I previously believed that add-ons were causing this issue, but it turns out I just got lucky with the lighting not being bugged, so I am reposting it.

If you look at the screenshots provided, you can see how patchy the lighting is, and in the third, you can see how the lighting SHOULD be, super dark, but for the majority of the build, that is not the case.
