Fix: Nuke Cannon May Change Targets While Unpacking

[commy2]

ZH 1.04

• The Nuke Cannon will target the nearest enemy while ordered to attack any enemy in range. If the auto selected target was close enough in angle, the Nuke Cannon will even waste its first shot before recentering on the ordered target.

After patch:

• The Nuke Cannon will no longer defy the player and change targets on its own. Attack move and Guard mode still work the same.

Note:

• This was not an issue in CCG, because NotWhileAttacking did not exist, or rather, was implicit for every unit.
