The new city building system has a massive flaw. I built my city two tiles away from both a forest and a river. The game still has Logging Camps / Docks that have forest / river prerequisites. You can build them if you have a building adjacent to a forest / river, but now since the game is in auto-placement mode, you're at the mercy of the AI tile placement.
Worst of all, I noticed that you you can actually game the system by putting a lot of buildings into the queue, and when one of the building gets placed to where you want, you cancel all the others.
I didn't test if putting units next to the city to block tiles affects the automatic tile placement. If it does it's even more cheesy.
I can't for the life of me understand why this tile placement thing has to stay in. You go through insane amounts of trouble to keep the system, and I don't understand why.
