Fix Sion
Aye this has happened to me multiple times, one on summoners rift the other ARAM . Whenever I use Sion's Q and Cho' Gath uses rupture, not only it cancels it (which it should) it cancels it for the whole game. In order to fix it I have to disconnect and reconnect, and that can be dangerous if we losing or if it is a close game. So I ask Riot to please test it out and fix it.
