Ok, fifth time trying to make a route and it does this.

Why the hell does it do this? I did not once step of the street, and neither did my in game character, but the route just snaps completely outside for some weird reason. Multiple times it did the opposite and, even though my character was on the street, the route snapped into the middle of some houses. I just don't get it. I was walking extra slow too, but it always does this.
