Aeon t1 pd building animation issue

The Aeon t1's building animation/blob has so little height that most units shoot the floor when they shoot at it.
I've had it with an ACU before but in this replay it's quite stupid, please fix so units don't stand there and shoot the floor all day, its really frustrating as the pd is quite high on the target priority list.
