The players on the Square Enix Tomb Raider forums speculated that an inventory bug caused the Dr. Croft and Completionist from unlocking. Every item in the game shares space in Lara's Inventory.

Most players, like me, more likely went OCD and bought the ammo pouches, crafted outfits, etc and those took up space needed for the Artifacts.  Why maps showed 100% but Game itself showed 99% and below.

I tested this hypothesis on a 2nd play through on Xbox. I did these things in my playfile:

 1: Did not craft any outfits

 2: Did not buy outfits

 3: Did buy Lockpick, Knife Upgrade, Rope Ascendor

 4: Did not buy weapons, ammo pouches, or weapon mods.

 5: Did all 13 side missions, and did Bullseye challenge in Croft Manor Flashback

I just completed my 2nd game with the above, checking each artifact by looking in collections after picking up, and i unlocked both Dr. Croft(max collections) and Completionist(100% game)

 

In conclusion, the hypothesis was correct. There is an inventory bug that Square Enix has not yet fixed of every item in game sharing the same bag space.  For those having difficulty getting 100% game progress, follow the above on a vanilla play-through (NO NG+)

 

So in closing, start a new game file and DO NOT CRAFT vestige outfits, DO NOT BUY outfits, weapons, ammo pouches, weapon mods,  and ONLY PURCHASE the Lockpick, Rope Ascendor, and Knife Upgrade. Do every side mission (two give artifacts).

Do Bullseye Challenge (hit targets with med ball) in Croft Manor [Just to be safe]

After picking up each artifact, view the artifact and as Lara reads the description, push "View Collection" and make sure you see it in the list(s).

And finally, have fun and hope this wall of text helps you to get your two 100% achievements/trophies

God Bless

That's great news! Thanks for sharing this info.

 

You're welcome. When my Manko Tunic went purple heart, and the two achievements on Xbox went from 0.74% to 2% of Xbox players unlocking...I had a feeling they were on to something with the inventory thing.  But all the above gave me 100% map and 100% game completion.

so hopefully it helps other people having the same issues

well done . . . shouldn't be this way, though

Thanks. And very true. But for OCD and impatient people like me, this is a almost sure fire way till Squeenix decides to fix it .

Thanks! This is good to know.

I'm on my second play through on Deadly Obsession, and had started collecting everything again -- It seems that it stopped counting relics, murals and documents after completing San Juan and heading back to the Hidden City for me -- And Hidden City was the only place I just had a few things left to collect to 100% it as the last area.

Looks like another 400 to collect on another play...

Sorry to hear that morph ?  Hopefully Squeenix fixes all this soon.

But I guess silver lining is all of us are getting our money's worth with all these playthroughs lol
