I don’t understand exactly: Did you move Steam itself? When you’ve moved your games it should be enoguh to go to Steam -> Sttings -> Steam Libary and Add the new location as Libary…
no Steam is running fine, but Lutsi doesn’t list all the games I’Ve installed. And none of one particular folder. It shows that I own them, but not that they are actually installed. I wonder how I can tell Lutris where to check.
