Problems with Detection

So in my game there is a defense named “Toy Brick” this repeatedly spawns “Brick Attack” on itself. But my problem is that any enemy (Orc for example) isn’t detecting the brick attack at all, in the enemies code you’ll quickly see where it detects it, but never does it actually take damage or trigger. This doesn’t work, with Collision, Proximity, or ray-cast. So at this point it’s just another unfixable paradox in my game.
