The bases are loaded and the batter has a count of two and zero.  The next pitch is called a ball by the home plate umpire.  The batter, believing it is ball four, walk/runs to first base and all of the base runners walk/run to the next base.  The umpire neither makes a motion towards first base nor says "ball four".  All of the base runners advance to the next base without being put out.  After all of the runners advance, the home plate umpire discovers that the pitch was only ball three and asks that the batter come back and resume her at bat.  Are the runners that advanced sent back to their original base or do the runners advance and the run is scored?  If the umpire puts the runners back in their original position, does it matter if the runner from third base touched home plate and then ran out of play?
