What they are talking about is this:

After grabing the sternwheel of the ship in order to steer the ship, you will be fine for a while. Then, there's suddenly some fort of offsynching with the movements of players and ships that causes them to get warped to the front of the ship, where it looks like they are still steering it. However, you cannot steer this way, and the ship will continue to head in the path that you were before you got warped to the fron of it. It used to be to where a person could disengage from the sternwheel by pressing a few buttons, but now that doesn't even help. Also, the rigging in the decks of certain ships don't always load, and a player has to lay down an item and grab it in order to get back up. I've also heard that the above-deck ladders on the sides of a ship aren't working properly anymore, either.
