The second player on my server can't see the ploughed earth, which makes it almost impossible to tend to the plants correctly. I'm the host an can see it perfectly fine. We're on the latest patch version.
I often have a completely black screen after sleeping on my multiplayer server. I can still see my mouse cursor and hear the game, but I'm left to exit to the main menu and reconnect. The other player doesn't have the problem when it occurs to me.
