Boats disappear every single time I jump out. If I log out and then back in, they will be there. Also if I leave the chunk and come back and load it the boat will be there. I am playing on a friends Bedrock Realm.

I video captured the issue but it is hard to explain with just screenshots. My captures exceed the file size limit. I could try to frame by frame if you need. Or if there is some other way I could upload a 45 MB clip.
