I noticed that when placing a defend location flag in D3002, there is now a handy AoE overlay that appears. It seems to use the same visual overlay mechanic as stockpiles and pastures, which remain partially visible after being placed. Unfortunately, if your defend flag is placed above ground level, that overlay starts to look funny floating up in the air.
Which leads me to my second issue, the AoE zone does not drape over the landscape to account for building height, and the surrounding terrain, it seems to remain static at the height of the flag itself, which makes it difficult to tell exactly where the leash zone will be. Essentially, as a player placing a defend flag on an elevated position, I need to know where the zone is on the terrain below the elevated position. As it is now, that zone floats entirely at flag height, making that sometimes difficult to determine. See screenshot below.
