Offline mode issue

So, I have this problem with the recent event. The point is: I play the game for the first time and I want a vanilla experience.
I tried to follow the anti-Bloody Harvest advice and play offline.

And guess what: the game dissapeared from the launcher. It says I have to download it… while at the same time it allows me to unistall it.

What The eF?! Is this the sign I interrupted some download when I went offline or what?
