Twitch ult cannot hit enemies at point-blank range
Just witnessed this bug in a Dominion game. Our Twitch kept getting jumped by Lee Sin, activating ult, and then dealing no damage despite it being an autoattack. It wasn't armor or anything, either; Lee Sin's health flat-out wasn't going down.
Repro steps: -Play a game with Twitch. -Reach level 6. -Move into sub-melee range (as close as possible; Phantom Dancer might even be useful here), activate ult, and attempt to attack the enemy.
