BattleRoyal : Unable to report player (cheaters) that are OUTSIDE of our Squad.

I was in a cool battleroyal round with skilled peeps.
This guy shot us through walls, all of us. There wasn't any spot and he was clearly marked as behind it, like 200-300m far. Also, a few seconds after, the game ended and his nickname was displayed all over the screen as if I was teamed up with him x3. It was very weird, felt like "I **bleep** up, let's terminate the server" - "remove all log" type of things. Not sure if it's doable but yeah. Never seen that before.

I've tried to report him on the game directly but in battle royal you can't report UNLESS it's on your squad OR the squad you're spectating while dead.

Either way, ultra weird, hopefully this guy get caught
