I've noticed a tendency of the client to crash when the character is exiting a ship or zepplin. This has occurred twice in Theramore and again in Rachet for me on the boats, and on the UC > Org zepplin. The client will freeze for several minutes, and may then return to the game, or it may crash to the loading screen with a disconnect message.
