I understand that you probably won't believe it, but it's the bitter truth... I've double-checked this many times while flying in an empty cell... I had three panic attacks and fell into a coma for several weeks while I searched for all the information.
1 first: if you go to the configs for flattery, you can find that the space is not in the usual number of coordinates for 2d games like x y x y z, which means that the game is in 3D
2 the second: I turned on my free camera with the help of cheats and was able to fly in 3D and see what was hidden from the eyes of an ordinary player.
3 Third: you have to take my word for it because my mom told me that I never lie and I'm a smart girl.

That's all I wanted to say... Drink a sedative and hold on
