I first noticed it yesterday, when I awakened 4 relics, but was not given the duplicate shards.
I've been keeping track of my shards and embers since this started on Tuesday. It is just a visual bug.
I haven't gottten ISO at all. Maybe I'm dumb, but… I didn't get any of the ISO packs from the EQ either, unless I'm misunderstanding how those rewards work.
It's just a visual bug. Dupe shards are automatically added to your inventory.
a bug… add it to the list!
I assume it's 1 iso of each class shown this way to de clutter the UI
