As the title says. In a multiplayer game, the host cannot check the box for Custom Difficulty or make any changes to individual difficulty settings. The dropdown box for Story, Authentic, etc is available to change, but not anything below that in the screen. Is this intended? I would hope not, and that we could adjust individual items even within a multiplayer game we were hosting. Specifically, we wanted to turn on Simple Encumbrance, but this is not possible since it is a custom difficulty setting which cannot be changed in multiplayer.
the workaround is to have everyone quit, have the host load the saved game in single player, change the settings as you want, and then reload it again as a multiplayer game and your new settings will be there. I can't imagine that's as intended, as its super clunky but its how you can do it for the moment.
Thanks. I tried that over the weekend and was able to make the changes and resave the game for our next multiplayer session. Hopefully they see this and fix it as a bug. But appreciate the workaround for now.
