With the changes in 0.264 city building got even worse.
Now you can't build stuff out, till the one building you're building is built.
I.e. X O O O
where X is an existing building and O is a planned building isn't possible anymore. You can only build
thus making it necessary to build one building after each other, visiting a city each time something got build to select the next building.
I think though this is only a temporary change, since it is incredible frustrating, and I hope we will soon see a new system for city building and resource connections.
