Met a dude called Smiling Knight who was helping me on Apocalypse mode. Guy was a total G, he showed me loads of secret paths and hidden routes. I stupidly changed the game to 'Offline' by accident and he got kicked out.

No Remnant 2 players are listed in my Steam recent players, and when I search 'Smiling Knight' there's like 200 results for that username. There was no in-game add button I could find anywhere, and no way to talk to him in-game.

Is that it? It's impossible to communicate with people unless you add them as a friend, but you can't add them as a friend in-game, and since his name is common... I'll never be able to play with him again? Surely a multiplayer game like this has a way to add players that I'm not seeing?
