Bug in CoC Clan War Battle: Hiding Air Defense building.

Hi, I want to advice of a bug happening since the last update. In my last CoC Clan War Battle, one Barracks building is shooting rockets to my dragons! I think there are 2 buildings in the same place, the Air Defense is not visible but occupying the same space than the barracks, hence not visible to the unexperienced eye.
Nevertheless, I won the battle, no harm done, I just wanted to inform you.
And if you think that this information is valuable, you could reward me with a same gems….hehehe….
Thanks a lot for your great game.
