Shadow Ruin + Arbiter grenade is what creates this I assume? Knocks Arbiter out of the move and for some reason keeps the game frozen in the shadow move camera angle and keeps Aganos invulnerable.
Yep, I saw this bug shortly after Arby’s release, as well as a few others on here, and we have all already reported it to the official bug-reporting thread in the suggestions and feedback sub-forum. Obviously it hasn’t been fixed yet, so go ahead and re-report it there to give the devs a reminder. 
Yeah I figured this had probably existed for awhile, feel like I’ve seen a video of something similar. I reported there as well.
