On pillars of gold the shield battery will leave a black mark when hovering over the terrain. Kinda like a black shade and is really annoying.
I had the same issue on other maps , it’s as if the shield battery shadow is being repeatedly drawn or something.
On all current maps I have noticed that when selecting shield batter structure, prior to placement on map, that a shadow of the battery is trailing the position of the on screen mouse.
The battery also trails with shadow prior to placement on the map with a long delay before the shadow fades away.
I hope it isnt creating issue on performance.
