I was transporting one villager in a boat to my house, I got it where it needed to be and exited  the boat when he moved back to the water. It wouldn't let me break the boat, or get in it so I saved and quit. I got back in my game, my boat is gone, including that villager and the rest that were in my village (I had about 10-13) none of them died; and even villagers I had locked trades in with are gone
