Bug with Mordekaiser ghost.

Was playing Mordekaiser and noticed that when ever i ulti Azir and he dies, the ghost spawns and follows me around but i can't control the ghost with ALT + Click like i normally can when killing other champions.

This happened twice in the same game. I was forced to ulti other champions instead so that i could use the ghost to push towers.

3 guesses why i was using my ulti on Azir in the first place!!! He's pretty damn strong!

Please fix as i play Morde allot and will no doubt come up against the golden metal chicken again.
