And in either case, an In-Game Bug Report (IGBR) should be opened using the F8 key. This will give the devs notice of the issue and provide the game files and a screenshot (providing you don’t uncheck those boxes).
I figured it out. After killing all 3 omens the woven echo goes directly into your inventory. So I went into my inventory. dropped it on the ground, picked it up and the quest progressed. Kinda dumb, but the act of picking it up off the ground is the key.
