The encounter layouts in RSR seem to be missing quite a bit. I don't know if it's things not added or version changes.
In "Snippets", there's no indication of which building they intend to be the barber shop. Sure you can just pick one, but then you end up with a possibly arbitrary balance as you choose how many alley entrances you want.
In "Haven": D, the vines refer you to a nonexistent "S" on the map. D4 refers to a nonexistent D5.
I recall the other two having similar consistency issues with their maps as well.
