I was playing a multiplayer game in a shared world and then when we quit out the game and tried to load it back up it said that we did not have the primary save because it was either deleted or I was removed.  I had to do a standard copy. Is there a fix to this yet?

I have this exact same issue, I've tried multiple different things but because I shared the world with them I can still play it but it doesn't show the saves going to my thing as well and still won't let me play. Even if I make a standard copy and try to make that a shared world my game just crashes with the same prompt.

Yeah mine was doing the same but it wouldn’t even let me create a shared copy from the game.  It says it has to be done from the main menu, but I can’t do that.
