Reflections missing on door in Ahnonay cathedral

This has been discussed in other threads - I want to track it so it's not lost.

On both the Windows D3D and Mac Metal clients the reflection on the door in the Ahnonay cathedral is missing. The cubic texture that is being sampled is black.

It's unclear to me if this is an engine or an asset issue. The same issue appearing in both Metal and D3D - and reflections still working elsewhere - makes it seem to be an asset issue. But we should track that down.
