UPDATE: Well I have picked up Archinist (can't spell atm) archives and they are now counting.. lol
So this has been fixed properly. I got the challenge and now I am working on Sentinel archives and that should give me the trophy and the platinum.
UPDATE: GOT ALL THE CHALLENGES, GOT THE "NO STONE UNTURNED" TROPHY AND GOT THE PLATINUM...
