@SimplyJen I have ellacharmed's Bridgeport. It doesn't eliminate the elevator issues, but it does eliminate the routing issues on the roads that aren't properly connected.
My favorite worlds to play in are my own CAW worlds, Crystal Falls, which is an edit of Sunset Valley, and Brighton, my edit of Appaloosa Plains. I have exactly what I want in them, and the community lots are organized realistically, not just plopped down wherever there is an empty lot, like the game does with the venues from the EP's. But of the EA worlds, Hidden Springs remains my favorite, because I love nature, and the natural scenery in HS is so beautiful. Maybe someday I should take it into CAW and rearrange things so I can get the lots I want in it, located where I would prefer them to be.
