Howabout NO you crazy Dutch bastard. I always wanted to do that.

Allright, UMS is gay, but anyways, how you stack is you get your unit, ghost or whatever, and then you move him into the lights out section. But before you do that, click on your drone and hotkey him. Then after you make it lights out, go to where your probe whatever is and click what you want to make. You cant see the unit but you can see what you make. Then just build it you wont see it and it wont attack or nothing untill you turn your lights back on. This is how you stack cannons anyways.
