My sisters and I are playing and then they die.  Then, when they respawn, they just lose connection and get kicked.  I do keep an eye on the game output and something did happen when they tried to respawn.  The image I provided happened twice for each player attempting to respawn.

I also just found out that sometimes it would throw the error once but not kick the player.  Other times, it's normal; the player respawns with no errors showing up in the output.

I'm not sure if it happens often or rarely yet, but I will let y'all know when I know.
