The skyscrapers are located in a separate city in the desert. It is located in the southwest corner of the map. What you should really look at is Perishton in the northwest corner of the map. It's a completely different city now.Skycrapers like they had in A16? I haven't seen any, but admittedly haven't migrated far from Diersville.
I really wish this was an option you could set. Once you get past day 42 or so, your base is so solid that a week is more than enough time. Having that surprise lightning at 1800 when you're out doing a quest, midway through the apartments? Jeeze louise.
