you need to do go in "AppData/LocalLow/Arvus game" after that you go in the folder of the previous version of your game copy the three files "Player-prev.log, save.json and Player.log. Now go to the newest version of your game folder and then paste the three files and it's done !
I followed what you said but now my game wont start?... How do i fix that. It wont start with those files there, but will without them there...
Edit: Managed to fix it, Tried to extract the game into a new folder and try it in the new one and works now. Not sure what broke it in the first place. But this worked now. Thanks for givin me the steps
