Try to add the events detectors embedded with the maneuver by yourself
into the propagator when you add the maneuvers.
The propagator loops over all force models to gather the force model
specific detectors at propagation start, but not afterwards, so if
you add the maneuver after maneuver start, it will never be triggered.
