Skybreaker Mortar Soldier/Kor'kron Rocketeer Not Using Rocket Artillery in Gunship Battle

The Problem:
During the Icecrown Citadel Gunship Battle encounter, the Skybreaker Mortar Soldier (Alliance) and Kor'kron Rocketeer (Horde) adds are not performing any actions. These NPCs are supposed to engage in combat, but instead, they remain idle throughout the encounter.

How it should work:
The Skybreaker Mortar Soldier and Kor'kron Rocketeer should actively fire Rocket Artillery at the opposing gunship during the battle, adding an additional layer of threat and strategy to the encounter.

How to reproduce:
Enter Icecrown Citadel on the Test Server.
Start the Gunship Battle encounter.
Observe the Skybreaker Mortar Soldier (Alliance) or Kor'kron Rocketeer (Horde) adds.
Notice that they do not perform any actions such as firing Rocket Artillery.
