In the Operative tab while on ‘The Mourningstar’, on multiple characters, the Loadout (including both melee and ranged) and/or Cosmetics tabs have the yellow dots indicate new items without indicating which items they may refer to in the scrolling list.
After selecting each item in those inventories, the yellow dots remain.
We are aware of this and will soon be implementing an option that allows the user to clear new notifications themselves, which will provide a solution for this.
