Ragnarok singleplayer data has moved.

SteamLibrary\steamapps\common\ARK\ShooterGame\Saved\SavedArksLocal

Within this folder, move your Ragnarok save file and player data (LocalPlayer.arkprofile) in SavedArksLocal into it’s own Ragnarok folder (the folder will be created once you load Ragnarok again for the first time since the patch).
