Xbox realms observer operated flying machines do not work properly.

flying machines that are triggered by observers and ran by sticky pistons and honey or slime do not work. they do not support the weight of a player only being moved forward or backwards by a few blocks before stopping or changing direction if that doesn't happen the observer separates from the sticky piston and the vehicle doesn't move. with out a player on top of the vehicle it seems to move a few blocks then gets confused as to move forward or backwards or just separates at the observer.
