Just encountered this, using DX11. Maybe useful for the devs: the walls and floor and my character model loaded back in when I changed my camera angle so that the fires in the kitchen (which were flashing erratically) were no longer in frame. UI was still in quite a state, though, and prevented me from using the in-game bug reporting.
There must be more to it than just the fires, though, because Special Collections is also mostly a void.
