Game Over Bug! [Gameplay]

Not sure what the Bug is but i was just in solo queue Ranked game that consisted of the champions Sivir,Syndra,Vi,Azir,NIdalee on one team and the other team consisted of Ezreal,Braum,Lissandra,Jax,Vel Koz and around the 20 minute mark i got kicked from game tried reconnecting and the game no longer existed. So somewhere in the game or in one of those champs there is a bug that just cancels the game. Sorry couldn't be of much help.
