well i mean it's known issue, but that's pretty much for all aeon building. Kinda wanted to look into it at some point, but i'm not even sure we can do something, since the unit is under the ground, and gets lifted up as you build it. The collision hitbox is good though, so maybe we can change the target bone only when being built. But it's just speculation so far.
