Azir ult didn't push back units after Zhonya use.
League of Legends Match History
[GAMEPLAY] We just saw a bug on Azir ult. Not sure if it is a one time issue, but it happend very clear so everyone noticed. Talon chased Azir and teleported on him with e, with difference of 0,2s azir uses ult to push Talon back and insta Zhonyas himself. Ult moves forward pushing back creeps, but stops "pushing" effect at the same time he clicks Zhonyas. So only half of what was in effect area was moved by sand soldiers (before Zhonya). Game ended soon, so we had no time to check it.
