Just got the game, and am trying to play it with a friend. I am trying to host using hamachi, no hate please, and I see on screen "following peers are not responding unknown username" and I see in what I guess to be the chat his ip followed by was dropped from the game.
These are some images. We also tried with P2P ticked, and with various latencies.
