1.14.3: I have the issue with boats. For me, half the time, there is just a small delay, but I am able to exit the boat and the boat is still there; in this situation, the boat may disappear for part of a second. The other times, not only does the boat disappear and I need to log out and log back in again like others have mentioned, but before while the boat is invisible, I am stuck in the invisible boat, moving slightly (no more than 1 block in distance in any direction) and vibrating.
