Since you are the host you are automatically a "classic" admin on the "server/LAN Game" this means the server overwrites your permissions to the "classic" admin ones which set keepinventory=false.
To avoid that you need to set a proper server via steamCMD (see here for how to: Set up a server with SteamCMD ) and set in the server.properties file the settings_admins_allpermissions=false (default is true).
Then you need to create permission groups on your server similarly to I assume you have already done to test on your SP/LAN world and then add yourself and your friends to a permission group that includes keepinventory=true. This way you will have that setting enabled in game.
We each set keep inventory to true, but it does not work.
When you say you set it to true, you mean in the in game settings correct? These settings only apply in SP not Servers or LAN (including Steam p2p) games.
If we log out and load the game solo, the one we share or our own, it goes to true, and we keep inventory.
Yes in SP your personal settings apply but in Steam p2p or Servers the server side settings only apply.
yes to use the keepinventory permission this is currently the only way. To run a local dedicated server.
well it is not broke your friend if you don't make them an admin can have the permission (just add them to a permission group that has it set to true) only classic admins cannot use custom permissions and in the Steam p2p the host is a mandatory classic admin.
