I was doing the Tradecraft quest for the railroad, and at the end you come up from the basemant of Slocum Joe's. Right next door there is a laundromat which is not much more than a small room with laundry machines in it. Why is this something that requires a door and load screen to go in to? I've noticed a few other places like this, like the old corner bookstore and a few houses and bars. Why not just have them part of the open world?

Keep doing rail road quests and you'll find out.

console or PC? never happenes to me on PC. If PC, then it's your distance view loading most likely..
