I have warmode OFF for a reason. To avoid PvP. I was in Hallowfall doing the Nightfall event. Somehow PvP turned on while there? And I was killed right at the end of the event. I hit the boss once, but was killed by two others.
When I came back, I lost out on filling up my top bar completely and the boss kill. I didn’t get either item.
Why is PvP turning on when I have Warmode off? Now I just wasted an hour of my time waiting just for some troll to kill me.
Its a relic of how PVP used to work. You can still manually flag yourself for PVP outside of warmode, and if someone hits you they get flagged.
When I right click my portrait and click “Player vs. Player” is also Disabled. To be able to avoid this.
Did you fight back?
No, I ran and they chased me everywhere just to get the kill. I came back, rezzed to hit the boss, and was killed again.
There is a bug where after exiting a BG/brawl you can sometimes get flagged for PvP for 5 minutes. I noticed it during Comp Stomp, so I assume it must have a chance to happen when exiting a brawl/BG. Maybe that’s what happened to you and you didn’t realize.
I am sorry you were bugged obviously, that had to suck.
I hope you weren’t on that Rogue when they killed you, that would definitely be sad days…
Often times if you just exited out from a PvP match (BG/Arena) you will be flagged for PvP for 5 mins.
It doesn’t seem to be the case where you were in Hallowfall doing Nightfall so maybe someone toggled PvP on and you attacked them (they would be seen as Neutral) which flagged you for PvP.
You can’t attack someone who’s flagged if you are not already flagged yourself. Try, it won’t let you.
There’s some kind of bug or certain abilities that fail to check it, cleave onto a target that’s flagged, and then they kill you.
Yet another reason passive uncontrollable cleave is a plague on the game and should be deleted across the board.
^ this
If a person who is flagged for pvp stands on a boss and your moves hit them when you attack the boss, does that flag you for pvp?
Lol, now I want a toy that turns on PvP for other players.
It’s evil.
if you fly too close to an enemy Fight point you can get flagged.
If you entered or just left a free for all zone you could still be flagged.
If you rez a pvp enabled player you will be flagged.
if you heal a PVP enabled player you will be flagged.
if you get MC’d and hit an enemy player… there MIGHT be a chance you get flagged. idk about that one but it would be an easy thing to get over looked.
aside from that, you should still get boss credit if you tagged the boss as long as you didnt release. 
Cannot rez/heal flagged friendlies either, it gives an error and does not cast. That’s a common problem at worldbosses.
you generally can’t aoe someone who is flagged while you are not flagged.
I didn’t exit a BG/brawl at all before this. I had been playing for quite some time, so it’s definitely not the case here.
And none of these above happened either other than I may have hit the player when attacking other things… but that’s pretty easy to do with a big boss fight…
Most importantly, I hit the boss the first time, died. Released, hit the boss again, and died again as PvP remained on. I came back to the boss being dead and released. I did not receive the bonus box, because I was not in the area to get the percentage up at the top nor the loot because it just didn’t drop me anything at all as if I never hit it.
A really annoying thing to have happen and then get nothing at all when you’re specifically set to not have World PvP on.
I’ve had this happen on my Paladin. It has something do with Consecrate. Used to happen during Superbloom as well.
