Noc Ult Bug
Long story short, in a 40mn game, 2 times when I press my second R(spam actually) as Nocturne and he won't jump on the enemy, even if I'm in a range shorter than my Q. I'm pretty sure no one can silence me(Nasus, Yasuo, Ahri, Draven, Thresh) while I'm moving too. Haven't try it in Practice Tool, but I'm pretty sure Noc has a 10% chance of unable to use his initiating part of his ult.
