Commander Space Ship Dummy Causes Game To Never End

When destroyed, the Nomad ACU's ship that follows it around never leaves, so the dummy unit it is/attaches to stays alive and owned forever, causing a player to never be defeated on Annihilation

Start by locating the Nomad ACU and the ship that follows it, then trace what happens to the ship and its attached dummy unit when the ACU is destroyed. Reproduce the issue in Annihilation and verify that destroying the ACU also removes the dummy unit so the player can be defeated.
