I myself have lost my arkprofile twice over the life of ASE, losing all my notes/tames etc and having to restart the slow process of completion. Once to a busted drive and once to it just randomly disappearing, other times I always have to remember to back the file up when upgrading/moving pc's.
This is certainly not unique to me https://www.google.com/search?q=PlayerLocalData.arkprofile
Would love to see this brought to the new Ark. Would also love to see it back ported to ASE
Thanks!
