[GAMEPLAY] Rare Kalista freeze - video evidence

There is a rare bug on Kalista, where she "freezes" mid-pose, stops responding to inputs, and stops autoattacking for about 2-4 seconds. This is not the result of crowd control or lag. Taking damage does not unfreeze her, and she may die during the freeze. Other players in the same game report seeing the same thing that the Kalista player sees (she just stops and stands there, as though a "Stop" command has been issued, even though valid targets are in autoattack range). I roughly estimate that this bug occurs about once every 3 hours of play on Kalista. I first noticed this bug after the patch that changed attack-move and attack-move-click to target nearest to the cursor, rather than nearest to the champion -- but that may be unrelated.

Short, 30-second video showing the bug: http://www.twitch.tv/cblazer/c/6989783

To replicate the bug: Unknown. But I am constantly clicking move and attack-move-click, per usual Kalista mechanics. So every time the bug has occurred, it was in the context of attack-move-click spam. I suspect it has something to do with attack-move-click and Kalista's uncancelable autoattack animation. But who knows.

I hope the attached video helps you diagnose this bug.
