Azir Unable to Attack Inhibitors

I just picked up Azir and I have noticed a glitch where he cannot attack an inhibitor is a sand soldier is too close to it.

I have replicated this in bot games to confirm that if a sand soldier is summoned next to the inhibitor, trying to auto-attack the inhibitor will result in the sand soldier animation going through but with no damage.

I hope this is fixed soon. I understand that the soldiers cannot attack structures but Azir should at least be able to use his normal auto-attack on inhibs when sand soldiers are around.
