So here goes a better idea: Is obvious that when the creators of the game designed it, they decided to have this "ideal feature". But in practice it is very troublesome for all of us. So why not have a selector switch? AI or user, control of points... On this matter, look at a set of points when a train passes over them.. They change! (automatically!) This is nonsense. Some cars have the track attachment point of the boggie located so that when the points change, the car still is passing over them, making the train to derail. Well, sometimes! I think everything is related to the way AI functions over or with points. Just a thought, but yes, it has to be fixed one way or another..
