Doesn't look like they unlocked for anyone:
Lost Treasures Achievements not Unlocking
usually doesn't update till the next day
I'll be getting all those achievements and I checked them every month for progress updates and they started kicking in 14ish-24 hours after the ledgers close
also they don't all update at the same time sometimes some update 5 hours or so later than others
these are currently unlocking for me 12 hours after my original post
