Azir Tower and Morde Ghost

I played a game as mordekaiser today and noticed some problems with Azir. First, his ghost from my ult was unresponsive and would not always follow my alt+click instructions. This was especially apparent when I tried to order it to attack a tower.

Second, during midgame azir created a tower, and with 1 hit it managed to do 900-1000 damage to me . I am pretty sure this was not intended and no one else seemed to have this problem, so I have a feeling that both these problems are in some way related to Morde as a champ combined with azir.
