I noticed when I played, my fellow Asherton's would go to the diner but exiting the back they would have no pathway (just stand there at backdoor with footprints crossed out).

Going into Edit Town I deleted everything on the lot and replaced the diner more into the middle of lot. Hope this helps.

Aside from lots im not on looking like blue square holes, I love the small lots. All day today I've been getting creative with the limited space.
