This post will contain minor spoilers. You've been warned. When redeeming Lost Ghost Traces to Eris, I found the Ghost in Anchor of Light, whose dialogue identified itself as Jax, Eriana-3's Ghost. Despite this, the Lore entry I obtained for finding it was "Ghost Fragment: Lonesome Ghost". Further, when redeeming a second Lost Ghost Trace at Eris for the dead Ghost located in the Circle of Bones, I found a dead ghost who spoke of missing a guardian they'd never found, and yet I obtained the lore entry "Ghost Fragment: Eriana-3's Ghost". tl;dr It seems the lore entry rewards for finding Eriana-3's Ghost and the Lonesome Ghost are swapped. This doesn't "feel" intentional. Thought I'd report it here for Bungie to see. Thank you for your time.
