Twice now during the final boss, I will deepsight to see where I need to kill Vorlog and no lines in the triangle will show up. I can still see the black orbs where you're supposed to imbue the Vestige, so I do those and the runes DO show up. HOWEVER, after I've picked up a Vestige, I cannot imbue it and just I just end up dying to the timer. This has ruined two solo flawless runs thus far, wanted to put it on Bungie's radar
