[CLIENT] Told upon login that I have received multiple key fragments, only one is added to loot

Several times now I have logged in and been notified that I have received two or more key fragments, but only one is added to my "loot" tab. I don't know if I'm not getting as many fragments as I should, or it's just bugging out and telling me I've gotten multiple when I've only received one. I think this has happened for the past ten or so times I've logged into the client, with one exception where both key fragments appeared in loot.
