Once I was playing on our Xbox world with my brother. I had a cat named Boobley in a boat and i was swimming in it from savanna to a jungle biome.
I parked the boat, but then it 'disappeared' like it was unvisible, with the cat! (I still heard his meows)

I was forced to restart the world, after what Boobley and his boat appeared. (This also happened to Sophia, the second cat)

The issue happened on 1.18.0 and 1.18.1, but i wasn't already using the world during the 1.18.2 update so long that certainly i don't know does that issue still exist.

Thanks!
