I have been playing on my Xbox 1.17.4 world and am traveling with a wolf pack. I needed to transport them across a lake and so far only the babies have made it across without deletion. When I exit the boat before it has fully stooped the boat and the full grown wolf disapers without a chat message or anything along with the boat. Nothing is dropped. You then have to leave the chunk and reload it to get them to show up again as if nothing happend. (This only seems to happen if you leave the chunk)
