I'm currently using your version of Sunset Valley, and something prevents my sims from moving in and out of Doo Peas Corporate Towers lot. If I move my sims on that lot via teleport, they have no problem entering the building itself. Does anyone else experience this?
I did have that problem with an early version, but thought I had fixed it in the current version of the world. I haven't had the issue at all since. You could try reinstalling the world and clearing your caches, or you could try removing and replanting the lot, just be sure to save the lot to the library first.
