Guild Wars 2

I didnt see a topic about this one so I thought I would post, if there is I do apologize.

I’m sure many has had this happen, but during the parts where you gotta kill the harpies to advance forward, when I get knocked down and go back up, normally all of them go invulnerable to me, so I am of no use to my team with damage. This happens at both times with the harpies(at the start and near the end)

Been alredy stated several times. Ignored until now.
