Today, I decided to see if the terrain around the bedroom repeated or not. It does, but weirdly.
There are shadows for interiors that do not exist, I assume this is because, when you light the mission, it lights the terrain, and when you repeat the terrain, it also repeats the shadows because they have become "branded" onto the terrain.
Also, on my way to find out if the terrain repeated or not, I realized that, when crouching, jets do not come from your feet, but some place... else.
Both things described above are illustrated in the following screen shots.
