My friend and I have purchased the game, specifically so we can play multiplayer. The fact that it does not work is something I would consider completely game breaking. We spent 2 hours, and eventually got it to work with a VPN. But 4 hours into the save, game crashed and 3 hours of attempting to fix it, we are still unable to play. Tried new game, both tried hosting, reset of router and PC, with and without the VPN. But it has actually gotten progressively worse. At first we could still connect, but would get dropped shortly after. Then instant drop after connecting. Now cannot connect at all. I have seen people mentioning this from the middle of the week, but not a single notice from the devs to say they are aware of the issue and are trying to fix it. Despite a literal game breaking bug.
