I tried making my My IP address 127.0.0.1 and my friend connect on my locale IP but whenever I enter the game it give me only server browser without the game and error can't connect to 127.0.0.1 check project-bo4.json (I already edited both v4 and server to 127.0.0.1) ,, and I can't load game game using command console ,, it says fucked up assets :) .Like damn why my assets fucked up?
