Poro King Bug

In "Legend of the Poro King" mode our team summoned the king when the enemy were about to attack our Nexus turrets. It came up "Your team has summoned the poro king" then immediately afterwards it said "The enemy team has summoned the poro king" and the enemy king appeared then a couple of seconds later he disappeared, without the "dispelled" message that usually comes up when he is killed. It was a crucial time when we needed our king to help us defend and as a result of not having the help they took both turrets, this bug basically lost us the game.
