Azir soldier's auto-attack bug [Gameplay]

When auto-attacking with Azir's sand soldiers, sometimes they just skip a turn. I hear an auto-attack noise, but the soldier's attack animation doesn't proc, nothing takes damage, and the timer for auto-attacking resets (basically it keeps pace as though it just successfully auto-attacked).

This usually happens to me 2-5 times per game, mostly happening in the laning phase when I place a soldier or two in the middle of an enemy minion wave. This bug has been proc'd both when targeting an enemy champ and when targeting minions.

Cheers

Edit: It occurred to me that there are further bugs in Azir's kit - some that I have witnessed and some that others have. http://boards.na.leagueoflegends.com/en/c/gameplay-balance/kEMIZMTx-fix-azir-and-all-his-bugs-already?comment=0005 wrong section, but valid points.

I'd like to add here that sometimes a dash can move past Azir's wall as it is approaching an enemy dashing champion (while it is solidified and moving). I have personally seen a Vi do it, and she subsequently wrecked me (as she does).
