Hi,
If I try to play a scenario arma3 try to update all scenarios from the workshop but if I have no internet connection it load until 7% but not more so I can't play and load scenarios in Steam offlinemode(no Internet connection)
Because of that there is no scenario available, therefore it's not possible to load the savegames.
I would suggest to add a load button in the mainmenu, at the moment its very uncomfortable and confusing :) (should not require an update of the steam-workshop scenarios)
sorry for my bad english :)
