Am I the only one that builds an urban zone, and destroys everything around me? I have one save where I'm about to take down the pharmaceutical tower because I built in an army barracks that spawned on the opposite corner. They render the distant POI at some point during the generation of the world, so there has to be a way to regenerate those things. Maybe make it update the models on exit, or on login, so you may have to deal with it for the current session, but the next time you log out, or in, it updates. I've done things like rebuild all the bridges in the south of navezgane, and renovate Departure one building at a time.
