Mr. Dragunov, I must say you were one of the best AI people I knew. I hope one day you return to Hive, as even now I wonder what happened to you. I hope you come back and with pride my most titular character is named after you for your kindness. Good luck, friend.
there are still people having problems creating an additional town hall ... here´s the solution:
Adding an upgrade to a building which can not be build, the "not buildable building" should be upgradeable to the new custom town hall
let me show it you in an example:
i want a new Main Building for Naga (Temple of Tides)
Town Hall (Human) -> FakeMain (This Building is Disabled = Not Buildable) -> Temple of Tides
