Please FIX 2 player issues

So many issues with couch coop

. Player 2 is default main player? Seems the game gets the 2 players mixed up and there no way to change party leader.
Player 2 has to sign out. Player 1 has to sign in and open the map, and then sign back out. Both have to sign back in, and if either player dies the game crashes.

How is this not noticable on GGG end? Even in EA, this is not functional at qall. Really unplayable.
