Shaco's clone bug and boxes targets

Helloooo, i realised recently that Shaco's clone can't attack the inhibitors or the nexus its kinda frustrating when you want to destroy it fast. And the boxes instead of attacking the tower which is the closest decides to attack a minion who is farther away. Links just in case:
