Was diving with the host player (my sister) and I moved the anchor. When she next entered underwater, she was spat out at the beginning of the map. I tried to move the anchor again to fix it and instead it became immovable by either player and it wouldn't let you exit through it either. Had to give myself fatigue to exit the water since there's no unstuck button for multiplayer.
