Ravana freezes mid-fight (hard mode)

During the last phase of the fight, Ravana knocked someone off the edge, seemed to chase after them, but upon directing his enmity elsewhere, he froze in place along the edge. At this time he also seemed to stop using all abilities and attacks.

Here's a small video I started to take of it after the bug had already begun to take effect.

This took place on the Primal data center on June 24 around 12:30 PM PST. It was the story mode/hard mode version of the fight.

I cut out some audio from the video since my friend and I were talking over VOIP and I didn't want to include that in the video.
