@ubi-wan Correction: I did get all 17 and turned them in. I just realized I had the Gorgon Shield in my inventory. Our conversation still has the turn in (17) line, greyed out, and I thought I had failed to turn them in. Thanks for the reply.

@ubi-wan I'm currently at 351 hours. The artifacts are still present in my inventory during an hour 208 save, "Homecoming", and an hour 319 save, "The First Night of Samhain". All other saves after that have no artifacts in ther inventory.

As for the final artifact, I haven't gone searching for it to yet. I thought I was doing a pretty good job with grabbing them as I went, but apparently I missed one somewhere.

Irecently completed the main storyline and had 16 of the final 17 Roman artifacts in my inventory. I don't know exactly when they vanished, but they're currently gone. I have the DLC installed but have not yet started the initial quest.

I'm playing on the Series X. The mobile beta forum is bugging out and I had to select Xbox One.
