I believe her actions were intentional and she stayed there because the remaining life of uras, the boss, was less than one bar. I lost the game right after the teammates came back.
I leave the decision to MS, but I just want MS to fix and prevent a similar glitch and maintain fair games.

Thanks Draco for the video. This was the exact same glitch.

I was the Ayana, antag. The last raider surrounded by devils were Mikah, the last survivor. At that time, to me, she ran into a devil in front of her, and I thought she was going to suicide, but right before the devil grab her, she went down the floor.
She spent there for the remaining 30-40 seconds and the rest of the game.

For some reasons, all devils ran toward her. If she grabbed a regular minion, and I did not see it for some reasons, there should be a statue and the statue does not draw attention of the devils.

I solo the map and went to the exact location, but I could not find a hole or gap in the map to cause a stuck or anything.

I have never been stunlocked by 5th counsel minions unless I was surrounded by 3 or more.

OK, thanks for your fill-in.
My PS4 is 3 years old now, but I have never purchased the same gaming console repeatedly because it's broken after years of usage. (I believe in Japanese perfect QA myth, and I always buy from Japanese manufacturers if I have a choice.)

Maybe it's time to consider buying PS4pro since its price drop was announced in Japan. Not sure if it happens in US, but I wait and see.

Anyone? Ever a similar thing happens to you??

I feel madness from them, and it feels right on Raiders.

At this point, you cannot make someone to listen. Only way you can keep up with MMR in a mentor match is to know how to carry a game.

Good news is, MMR does not affect any reward at this point. Low MMR, no problem.

They cannot listen to you because the voice chat is OFF by default.

If you cannot carry the team, form a group.
