How do you get the city menu into a game?

[Ape Drape 10]

First off... search returned a ton of unrelated threads.

Now that that's out of the way, I'm taking the Superpowers mp mission and making it single player. I'm wondering what I need to do to get the city menu working. I can't access it as a commander.

Oddly, it no longer works in the Harvest Red campaign either. Is this a 1.05 issue or is it something I have to script in?
