After Civilization 5, you can't click Immigration. Pick things, etc. What if I right-click the coil (I'm a novice)

Maybe you don't know much about this game. Immigrants are used to build new cities. To choose immigrants, click on itself, and click on the left to build a city, as shown in the figure.

"What if you right-click the line and draw a circle?" I don't know, but I guess this is your click to move, the line is your moving route and the circle is your destination.

"There is a box when loading, but it doesn't exist after madness" may be because of your version problem. Download the 674 patch of Civilization 5 on the Internet, decompress it and put it in the Civilization 5 directory to cover it.
