1st thing when things seem a little buggy is to reload your game.

On every world map there is the ability to scroll completely around the map. This results in a "map seam" in the pacific that runs from the Bearing Strait down past New Zealand. There is a bit of overlap in the seam to make things continuous so it isn't just a one pixel wide joint. When units stop in the map seam they can be challenging to click on because of the layers.

This is a known issue and is currently being worked on by the developers.

There are many alternate methods of selecting units when directly clicking on them is ineffective:

You may hold down the right mouse button and circle the area to select the units. Sometimes a "triangle" motion works better than a circle motion. This will make a gray shadow and select all the units in the loop. In the case of planes: Having the circle include the airbase or carrier they are stationed from is necessary. You will then need to use the split command to separate the planes from the carrier or units at the airfield.


Or, For units with a known designation, such as AB12, you can use Ctrl +F and type in the unitID to select the unit. You may be able to determine the designation from newspaper reports or from the unit list as if you were going to trade an army to someone in diplomacy menu. All of your units will start with the same letter code.

Or, The units can be selected by cycling through the units with the left and right arrow keys until the desired unit is found. Typically if you start by selecting a nearby unit and use an arrow key you will get other units within view. In some cases reloading the game will freshen the list and sort order, and enable you to find the unit easier with this method.
