Hello everyone, since a couple of weeks, i was trying to play fall of the samurai coop campaign on local network (offline steam) with my bro. unfortunately something ruined everything. by the way i bought this copy from steam... we cant resume the coop campaign Everything worked fine we start a lobby and the campaign worked fine, but the only problem here is we can't resume the campaign. I tried lots of thing and surfed on lots of thread but i found few things about what i need to help me. when we try to resume my bro can join the lobby but when i start the game to continue our coop it wouldn't start at all. It just bring us back to the menu after a short loading ?? that's really annoying also tried to rename the .save_multiplier by putting a name before the extension didn't work too.. I really want to play with my bro, but this problem ruined everything

Any help please
