This issue happens when Origins, Dehydration and Requiem are installed. If I save and exit the world while possessing a mob with Requiem (tested with zombies), when I try to reload it it shows an Invalid Player Data error and takes me to the multiplayer screen. If I go back to the world screen the world does not show up at all until I restart the game.
