Boats disappear when I get out of them

I hopped on an old world I've been working on for a while and I decided to explore a bit so I got on a boat, sailed a bit and when I got out and turned around it disappeared. I even made a new world and the same thing happened 2 more times. I think the same thing even happened with my bed. It wasn't very consistent so I couldn't get a video but if you wouldn't mind looking into it. Thanks
