Dumb question, the Steam Deck of the image is yours or you could never get it back? In a first instace I think that the Steam Deck in the image was yours.
Are you sure? I just tried disconnecting my console from internet and play some game for a while and then when the play time increased I exit the game and connected to the internet and the play time was actually the same that the previous one before I connected the internet.
I feel dumb for not checking that first, thank you!
