My ETW steam game now no longer play in offline mode

[Castout]

Today when I logged into steam steam was saying that it was updating platform. And after that I can't play ETW in offline mode?


Is steam moving toward SHV DRM?

I can play the game in online mode only and whenever I tried to go into offline mode this error would pop up



Is it just me?

Edit: Oh well it was a false alarm after checking file integrity something was redownloaded and steam now will connect to the internet when we try to play offline before switching to offline mode.
