Anold mesh light expect exactly one mesh error

[phillips.a.adam]

Arnold mesh light always shows this error:

00:22:29 1607MB ERROR | [htoa.object.light] Expected exactly one mesh in /obj/torus1 for mesh light /obj/Mesh

As you can see it even does it with an out of the box primitive shape.

Does anybody have an idea on how to fix this? I would assume that a single torus (polygon) is exactly one mesh???

If I try to repo "out of the box", I can't.
