Instantons with boundary jumps and spin magnetic tunneling were described in the magnetic molecules. The missing quench paradox in the magnetic molecules was resolved by the inclusion of the instantons. Instead of ten magnetic values that could be expected from the topological Berry phase between interfering instantons the tunneling between the ground Zeeman states of magnetic molecule was quenched at only four magnetic values. A formula for the location of the four remaining quenches was found.
