Every time the game loads a save or enters/exits a new location (like England to River Raids, England to Mastery Challenge, etc., anything that causes a new world to load in or out) the main longship resets all cosmetics to their default looks (everything goes back to the Raven Clan scheme). This does not happen to the River Raids ship, just the main one. The shield glitch from before has been fixed, but it's just been replaced by an even more severe one.
