[Gameplay] Azir, basic attacks deal no damage to creatures

Upon attacking a creature be it a minion, dragon, or red buff with azir's sand soldiers after a while of attacking said target they will take no damage from azir's soldiers. This effect seems to only dissipate after a short period of time, though during this time azir is being attacked by the creature, resulting in a loss of mana and health. The cause for this bug is unclear. Though from my recent games as azir it has happened at least 3 times per game. A replay isn't available as it was performed in a bot game. This may be a crucial factor as to the game type, but this is unclear to me.
