In the offline mode of Steam you run Dota 2, wait for the moment loading screen should disappear and get you to the main menu, but unfortunately the only thing you can see then is a small dialog window showing the small loading circle srolling round again and again with a tittle 'Connecting to the Dota 2 network.' and you can hear the main menu music playing and nothing happens even if you wait a day. which actually leads me to a question why only can't items in the armory be a content saved in your PC to you could use it while playing offline too (?)! :\ ). Earlier, there was no problem like this - you've just swithched the game on, got to the menu and you might have played against bots only, but still you were at least able to play (also without sets or items too, because those are saved in the cloud. After one of the last updates that fluently and clearly downloaded, I found out, it is unable to get to the menu when being in the offline mode of Steam platform.
