Invincible/invisible in arena glitch?

[TOK]

Anyone else have this happen? I was doing the arena battles and got killed by wolves. When I restarted the round, the enemies could no longer see me. They were still moving around fighting each other, but there was no detection indicator and they weren't doing the callouts for when they see you. I could walk right up and stab them.

I did a couple rounds like this, then blew myself up with an exploding barrel. After my death, everything returned to normal. Anyone else have this happen in the arena or even other area of the game?

Yes and when I went out to fight outposts it was the same , when I walked up to an enemy they said things like they do when you throw rocks . Cleared an outpost and a fortress without ever being seen . Turned off the game with out saving and all is normal .

Thats a weird one, I'd love to know what triggered that.
