Perhaps similar section of code to another bug (start position), but two oddities within this artifact:
When on the Load New Game option within playing a world for the first time (or loading with saves), if you hit [ESCAPE] instead of selecting a game slot to load, this will take you out of this menu (undesirable) and place you (in actual play) in a strange position in the game (not the start position)
Extra info: however, it does consistently place you in this position, must be recording the last saved position, even though it's inaccurate.
