Spot Lights Shutting Off when Directional Light Intensity set to 0

Unity Engine

I have one directional light (sun). I have a Sundial that switches my skybox from day-dusk-night. When dusk hits, the light intensity starts to lerp from 1.5 to 0. Everything works as it should.

I now have a prefab with lights attached that the player can insert. When dusk hits, the lights turn on, when day is reached, the lights turn off.

All lights are real-time and everything works as it should in the Editor.

For some reason, in a Build, when the Directional Light intensity goes to 0, the Spot Lights turn off.

There is no code connecting the two lights.

I fixed the problem by clamping the light intensity to .001f.

Is this a bug or a random light setting somewhere (using URP)? I have no idea why this is happening. Any ideas?

Another strange thing, when the directional light is rotated 180 (parallel with the XZ plane, the Spot Lights also shut off. Aaaargh!

Found the issue. It had to do with Quality Settings.

I didn’t know the Editor can show you different Quality Settings than what you build with.

The Quality Settings Matrix is really confusing since you can check more than 1 row in a column.
