In the Sims 4 my child walks all the way to the pier to go to school.

@Phantomlover1717 , that can't be right that "it's not a bug and happens to every Sim" since it only happens to one of her Sims and not the other.  It might usually happen, or it might happen to most Sims, or it might be that it is supposed to happen, but clearly one of her Sims has a problem, be it the female child that walks through the neighborhood to get to school and then back home, or it is the male child that disappears right in front of the house and returns the same way.😢  Most Sims when they go to school or work will disappear in front of their houses and reappear afterwards. So I don't know what you mean by saying this isn't a bug(?)  I felt that JenEarthDragon described her problem clearly.

@JenEarthDragon , this has not happened to any of my Sims, be they child going to school or adult going to work. The only time they run through the neighborhood to go somewhere is when I have them on a lot or in a neighborhood that is not their home, such as the museum, or Chez Llama, or SanMyshuno, etc.  In that case they never just disappear, they always run through the neighborhood to get to a point where they can "teleport" home; they never do that to go to work or school!  It is extremely annoying when you are visiting the Von Haunt Estate with the giant Hedge Maze!  I've had soooo many Sims get stuck in that maze, and run through the whole maze and then across the rest of the neighborhood, and end up being late for school or work! 😠  But that can be controlled by not going to the Von Haunt estate -- your problem is so much more frustrating because it happens every time at the home of the Sim, which means it is unavoidable until it gets fixed! 😢  I hope you figure out what the problem is soon!  Best of luck! 😉
