Dude... no one in this thread has provided a single argument that that turret "bug" was a bug except for saying Riot said so or by giving vague statements, so still appeals to authority. And what I'm saying is not voodoo science, it's quite literally testable: go into customs with a friend, play in practice mode, or play KJ for a while and you'll realize these are just the regular mechanics of the turret. It's just that, in this instance, 2 unreliable features of the turret triggered simulatenously which gave a "bug-like" response, but it's not a bug.
If this were a bug, you quite literally can't jiggle peek a turret that's standing adjecent to you since it will continue to replicate what happened in the tourney. And for Riot to blame FPX for that is EXTREMELY foolish since it's what they coded.
