Hawke liberator
Find a map that does not have the “Rescue the villagers and defeat harpy kidnappers” event active (this event is bugged and cannot be completed). Wait around the village and eventually the event “Defeat the kidnapping harpies before they reach the cliffs” will start. It’s an easy event, finish it and you will be awarded the trophy.
That’s what I had to do because the rescue event would stall and could not be completed. At least there’s a secondary option, just gotta be patient and get on a good map. Good luck!
Main: Neyrilla – Sylvari Reaper
how did you find a map that does not have the event? been checking for 3 days in a row? help!
And now, https://wiki.guildwars2.com/wiki/Defeat_the_kidnapping_harpies_before_they_reach_the_cliffs is bugged too. I waited nearly 2 hours to realize that it does not trigger at all because a harpie is regularly poping in the camp to disappear almost immediatly without doing anything.
So the Hawke liberator cannot be collected anymore. Wonderful.
