Syndra Ult Bug
Whenever Syndra Ults a target that is right next to her or extremely close in range (almost touching) she bugs out. After the ult she begins twitching around for a few seconds, almost as if she is avoiding minion block around her. I believe it has to do with how the orbs that fall around her are coded as minions.
I used the Atlantian skin when the bug occurred, however I think the issue is spread to her regardless of skin.
