Saw this bug or the first time yesterday night, was in speed run so no time to "/bug".
We begun DPSing the second boss of Hel Ra right side. After some time he usually runs to the middle of the room and then splits into 4 images. This didn't happen this time. Don't know if someone taunted him or what happened but as he was running to the middle of the room, he changed direction, ran left and then stayed there stuck while we where killing him. He did not split and if I recall well he wasn't even attacking us anymore either.
I was recording at the time so will post a video about this tonight here.
