Anyone find the last refugee item?
I think there are just two items we can find right now.
The others should become available to find as the story progresses.
It’s probably something you do after a reset or on an alt, like with the Jan living story achievement
To follow up, here is what ArenaNet said about those lost items (initially, there are 2). I highlighted the relevant part below:

You should have received an in-game mail directing you to the areas which you need to explore: Wayfarer Foothills and Diessa Plateau.
You should see a refugee camp in Lion’s Arch, near the Farshore Waypoint. By speaking to the refugees, you will discover that they’ve lost some items on their journey to Lion’s Arch. You can help them out by finding these lost items. Initially, you will see two refugees. When further phases of the event unlock, and the refugee area in Lion’s Arch grows in size, you will find new people to talk to who may also be missing items.
You will find the lost items in areas where the new Living Story events are spawning in the world, usually near the invader portals or invader vehicles. Note: in the event of a new build or server restart, the locations for the lost items may change.
So you shouldn’t be turning in the same 2 items repeatedly to get the achivement. You should only be able to turn in each unique lost item once.
