When I was riding on my boat in Minecraft Bedrock Edition and I notice my boat keep on disappear on me when I exit the boat. I tried this 3 to 4 more times and still ran into the same issue. Going in boat, then riding in my boat, then dock my boat, and then exiting the boat and the boat disappear. I just press down my right joy stick till it clicks to exit the boat and then poof gone.
