(Tested on Update 1.5.12.0)

Before reading further, do the following:

[1] Start the game and go to Play Campaign --> 8: Essential Personnel --> Select Mission --> Start Mission --> Press any key to continue. You should be at the deployment screen.

Throughout the following steps, do not pan, zoom, examine units, or anything else. You want to do the absolute minimum needed to reach your first fire phase.

Deploy all of your units near the top of the screen. It doesn't matter what units or where; you are never going to move or fire them. Press continue and wait for the A.I. to move and fire. Hit "end phase" to finish your move phase without moving anything. You should now be in your fire phase with a bunch of road hexes highlighted as possible targets.

Click on a road hex that is close to an Ogre and fire on it with a howitzer. It should work normally.

Now select the road hex that is right next to the lower left howitzer. You will find that you cannot fire on it. Cancel and try firing on the hex where the road crosses the track closest to the train. Note that all of the howitzers except the lower left one can attack the road segment.

Have you figured out why the lower left howitzer cannot fire? Answer in the next post.

(You might see it right away, but for me it took a while).
