Happy ghast freeze

When using happy ghast my game will completely freeze except for ambient and music until I forcibly close out the game. When reloading back into the world, the game will load me off the happy ghast dropping me from the happy ghast original place before the crash. Boats attatched with leads to the ghast will also break off the ghast. When approaching the ghast after reloading the world from the crash, the game sometimes will revert players and boats and entities to their original places before the crash.
