Anytime I am in a friends game and i go to enter caves, the game enters an infinite load screen and crashes. Afterward if i try to reopen the game it says it failed so I can no longer join again. This only happens when I am online in a friends game, hosting splitscreen on his console fixes the issue but prevents us from having more than two people on our team.
Play on a friends hosted server and enter a cave system. The game should enter an infinite loading screen and then crash. If you try to rejoin the game it will fail and you will no longer be able to play that game again. Not sure if rolling back the server to before you entered the cave fixes it or not. From what I have seen this has been an issue for a while and it would be great to have it fixed.
