I've got one city, and I'm trying to start another. However, after I find a plot of land that I like and click on claim, which takes me into the area where i should be able to start building a 2nd city, I can't. The road tab is red, and I can't build anything. If I had to guess, I think it's because I'm in spectator mode, but I don't know how to get out of that. Can anyone help?
