@Ubi-Bandicoot, My apologies for the late reply.
Yes, it happens every single time.
I visited the tunnel / room after some time of play elsewhere on the map and it was like in the video.
I then logged out and quit the application from the Xbox game menu. Started it again, logged in and spawned at the closest control point, traveled directly to the tunnel (about 200m from the checkpoint), and the room behavior was before. It "dissolves" as soon as you step in there.
