It's not a bug, what Chistopher said about adding pass_through into a
photons block within the media container is the answer. Just a thing about
how photons interact with objects. I guess the spotlight, being a source of
photons, wasn't getting into the media-filled box past that surface. Similar
to the camera being inside a nonhollow object maybe.

And the photon spacing can be raised to about 0.05 I think. Also, media
method 2 helps with the render speed because it definitely is slower when it
is working as expected.
