I asked QA to look in to this. This was the outcome:
Cannot repro this. However I think it might be the case of them changing character when they are returned to their keep.
So if I am Kerillian in my keep, I join another lobby where my character is picked so I have to pick another character. This will result in me becoming Kerillian again when I get kicked to my lobby.
So if I open a chest as (lets say Bardin) when I’m in another player’s keep and then I get kicked midway, I will be Kerillian in my keep. If I then look at my salvage section as Kerillian I will only be able to see Neckless/Charm/Trinkets that I got from that chest because I opened it as Bardin and any weapon in it would then be for Bardin and would not show up for me as Kerillian
