SetHeight() for actors works on game resets (Desktop or from the main menu) but not on saves within the game or quicksaves.

I'm also using the RaceMenu mod which uses its own setheight system. (I may ask how that author of the mod got it to stick through saves)

Mine works by altering the height after, but again it works great up until i try saving then reloading a game while playing. If I save, then quit to desktop or Main menu, then

reload the save. the player goes to the height specified.

How does one make it so the game recognizes setheight() through saves / quicksaves please?
