Left shows the way it should be, and right shows how it is currently.
The towers are placed 8 px too much to the south.
I think this results from the tower sprites being centered, and since they are 32x48 px in size, there is an 16/2 = 8 px unwanted misplacement in y-direction. It should be fixed by manually choosing the correct anchor point of the sprite (define offset).
