This is a problem that I noticed in the defence of Savannah a few days ago, so I don't know whether the latest patch took care of it. After deploying my land troops, there were too many unit icons at the bottom of the screen to all show up properly. I noticed that I could scroll through them, but the initial ones for ships would disappear, as you can see in the attacked image. Out of six ships only two show up. This made it impossible for me to unload some sailors to help out when the battle wasn't going too well. At another instance, when I refought that battle and could select one of the other ships, its icon was underneath the ship's crew information, so I couldn't select its row boat. I suppose this wouldn't be a problem for higher resolution screens (mine is 1366x768) but, then again, with enough units it might.
