A continuing report that, if a Player is on the same account continuously for 12 to 14 hours, that Player will lose his connection to the game (Lost Connection Error) and receive the error message "Invalid Name or Password" and be kicked out of the game. This happened to me without warning on 2/13/15 in the early morning around 7 am PST. I had been switching between Pirates in the same account so I never logged out of the game.
Be warned Pirates! Don't be in a battle land or sea when this happens to you! To prevent the error from happening, log out of the game after 11 hours of playing and then log back in. Otherwise, when you log back in, you might find yourself with 1 hit point and several of your Companions in Bed Rest.
