My defensive strategy is simple: raiders enter an opening in my wall, follow a little maze and then enter into the killbox: a line of spotlights to dazzle them and decoys to distract them while my turrets pump them full of lead. Meanwhile, my colonists are standing on platforms behind the turrets, ready to fire.

The only problem is, even with a clear line of sight and the enemy well within range of their weapons, I still get 'cannot hit target' notifications if I order my people to shoot the enemy. I've tried moving things out of the way, but I still get this even if there is nothing between my pawn and the enemy target.

The weapons they are using are modded ones added by a mod of my own creation, if that makes any difference.
