Catapults unpack when they are not on range

[tuxayo]

In the attached replay.

• from 28:20
• I order catapults to attack a tower. They move forward. Start unpacking.
• I see it's a bit out of the radius but I think it's just a bit wrong. (I heard towers shoot more far)
• But they don't attack.
• I order them again to attack. No attack happens nor unpacking to move forward.
• 29:25
• I order them to move a bit forward and re attack. This time they can fire.

place: top of blue player territory. Limit between blue and red teritory, the 4 catapults.
