I got to the skull cave on my second go and something happened that I remember from the first go.  There's an artefact but there was no text when I "opened" it and it's not at all obvious to me what that one was.  Subsequently there were two, I think, other pick-ups where there were XP but no written message about the pickup and no press "left button" to open that menu.  Any thoughts?

Are you talking about the photos that are added automatically as you go along? I'm not sure if those count towards 100% since there's really no way to miss them. They just appear when you reach that point in the story. Assuming there is no glitch involved, of course, which I guess we can't really assume at this point. ?

No, I don't think so.  Remember the discussion about the document and relic that were visible due to backpacks/maps but were "unfindable"?  It's the relic in the skull cave, you have to go to it and press Y (or whatever).  So after whatever-it-is that moves Jonah and Uchu to the Skull Cave from Unuratu's home (for no apparent reason as the latter is just empty and the former is not exactly hard to find but, well, whatever) Lara starts in the Skull Cave and there are these two things that can finally be unlocked.  The game's got bugs in it.

Actually something did occur to me earlier which indicates the 100% glitch might get fixed very soon; the DLC from the game pass includes outfits, right?  Well, the glitch prevents extra outfits being added.  So the shiny DLC might be bugged at the start with people not able to see the shiny DLC content - and that might just be so bad for a game developer that they'll consider actually fixing it.

The Document in Skull Cave is called :  Resist!

The Relic is called: Brigette Rosary (or something similair if my memory is correct)

If you wanted to check to see if the skull cave artifacts were added or not?

OK. I remember now. Sorry about the unhelpful reply. Still haven't gotten to that section in my second playthrough.

Thanks for that.  That's useful but I have a feeling it isn't that rosary - although I could be wrong - I thought that got picked up earlier.  There was no indication of what it was, no name or prompt to press the "left" controller button.  I'll make a note not to pick them up (if I do a third play-through) until after I've saved and copied the save file to another slot; then go outside the cave, run around and do whatever, then go back and open them.

It's fine, no need to apologise!

I didn't know if the relic was a rosary or not lol. after picking them up, i was so OCD about repeating the name out loud till I saw it in collections xD

So I remembered Resist! at least LOL

I have the PC version and ran into an issue when a document and resource were close together, and the TAB key option to read the document after picking it up didn't appear. There were a few instances of issues with adjacent objects, which I posted about in a separate thread. It is more of a problem if Lara is maxed out on the inventory for the resource.
