InitialSate before and after propagate

Hi,
I observe that the initialState is changed after calling propagate method.
I don’t understand why ?
Where is my unappropriated usage ?

Best,

Hi there,

by default integrator-based propagators reset the epoch to the last propagated date, so the initial state changes accordingly. If you don’t want this behavior you can call setResetAtEnd with false beforehand.
