I am playing Blood Moon, a night EFII scn, and as usual am in 2d mode. Initially I can see all units German and Russian in my line of sight as I should be able to. When a Russian unit gets waxed I end up with an orangish-brown square on the hex and cannot see what unit are under it unless I go to 3d mode. Then no problem.
When i go back to 2d I get the square again. I even get this with German units in the hex. Really irritating and hard to see what is in the hex and can only play this in 3d (which I really don't like as you miss the battlefield overview).
That would be the gunflash icon. If you want to stay in the 2D mode, I think you can use the Unit List to see what units are in the hex. Simply click on the hex and press U to bring up the unit list.
