riseofthecommonwealth

I've been playing Rise of The Commonwealth recently and I had an idea about making a special Mayor's Office plot. So instead of tearing down the previous-built settlement, ROTC town leveling would be minimised to just this plot, while retaining all features. The mayor's office would be upgraded...

i just downloaded this add oon as i thpught it would be fun to have the settlers build their own settkement but i cant find the city planners desk. ive done everything i could to find it, i even downloaded settlement menu manager. i really need help like did i do something wrong?
