Azir Sand Soldiers auto attacks

Since the new patch (5.3) I have noticed that there are bugs in the azir combo. Before the patch, you could easily drop a sand soldier (W) and quickly auto attack right after. Lately, most of the time there is a delay or the auto attack doesn't register. This also occurs when using his Q ability making the soldier dash to a target location. Right after the dash, I used to be able to auto attack immediately but now it either doesn't register right away or it doesn't register at all. This actually occurred several times in recent games where I have played him under the new patch. I know there were adjustments made to him but I feel like it created bugs in his auto attack sequence. I can confirm that it is not because people are out of range because I would hit them with Q and the auto attack would not register. I checked to make sure I was in range of controlling the sand soldiers and that the enemy was in range of the sand soldier auto attack.

To reproduce this bug, drop a sand soldier next to an enemy while right clicking immediately after. About half the time, it seems to not register an auto attack or it will produce a delay. This can also be tested with dashing a soldier to an enemy while trying to auto attack right after. Sometimes azir even uses the champion auto attack instead of the sand soldier. This attack is far weaker than the soldier's auto attack and makes a large impact on the game.
