hi guys, just download trails in sky 1st chapter since I really want to tried whats the hype about. everything was fine but my issues is seems I cannot save a file, whenever I tried save a file its auto gone, I even tried to save it and just back from save menu, and its already gone. tried to find any save files on my doc (appdata/roaming/local) seems there is none. so is there anyone has similar issues? I downloaded it from fitgirl, and since this game is not many people play (I assume) wondering if anybody can help me out.
+ another thing, how can I setup my dualsense for this? I tried dualsense and switch pro 2 controller seems cannot be used/detected at all. much appreciated!
