To put it short and simple, no matter what Y position you save at the game always sets you to 0.1.
Not sure how many of the official maps go vertically, but on the custom maps I am making, the player would be able to go to a position like 5,4,2 but the game would save it as 5,0.1,2 which is annoying if I want to save and come back only to find myself inside a wall block.
