Guild Wars 2

I am also having this issue, and while everyone here has described the issue, I would like to add what actually caused the issue for me. I was playing with a friend and helping them with their story missions. After we completed the mission Soothsayer checks for, I got a mail because I had completed that mission but had no active story missions (because I had completed my story already). I also attempted to correct the issue by replaying the final Heart of Thorns story quest, and while the mail stopped arriving while the quest was active, it started again as soon as I had finished the quest. Hope this helps you fix it.

I am also having this problem. It only happens in the starter zones and appears when my health falls below a certain amount. However it does not go away when I use the heal skill or my health goes back up. While the arrow is active I cannot use my “esc” key as all it does is cause the arrow to move up the screen. The only solutions I have found to remove it once it appears are to either re-log, or trigger a cutscene through a vista or story mission. And as stated before, it does carry over onto the world map when I pull it up.
