Desktop Moving Station Head Position Bug
Head movement becomes strange when in a freely moving/rotating station in desktop mode.
Issue seems to be caused by floating point error accumulation, problem is made worse by being further away from origin.
Returning to origin does NOT fix the problem. Re-entering the station does, until it happens again.
Issue persists after exiting station, is fixed by entering and then exiting a station.
Effects: All worlds with vehicles or theme park rides

Method:
Enter the station.
Fly far away from spawn (30,000++ to make it happen quickly).
When far away try rotating with the WASDQE keys, notice how the view position shifts awkwardly as you rotate.
After doing it a lot you should notice that your avatar's head and view position moves around a lot based on your look direction, even after you exit the station. (Check with mirror/camera)
Keys:
WASDQE=Rotation
arrow keys=Move
H=Respawn Chair
Space=Exit Chair
Technical:
station is just a moving transform, no rigidbody, moving in Update()
The bars in front of the chair are for positional reference, so you can tell the bug is happening.
Bug was introduced some time mid 2025.
