meep: bug: unknown src_time_id (missing registration?) when using mpa.FourierFields with yee_grid=False

[HIEROT]

I have read PR #1959 and am aware of the possible causes of the issue is that a chunk need to meddle with other chunk's sources. It seems solved, however, in the above PR, but I met this error again when mpi parallelization enabled. After some investigation, I figured out that it has something to do with MULTIPLE FourierFields parameter, which means after uncommenting the code below, the error raises when placing the adjoint sources.

    obj_list = [
        mpa.FourierFields(
            sim,
            vol_trans,
            mp.Ex,
        ),
        # mpa.FourierFields(
        #     sim,
        #     vol_trans,
        #     mp.Ey,
        # ),
        # mpa.FourierFields(
        #     sim,
        #     vol_trans,
        #     mp.Ez,
        # ),
    ]

Note that this can happen even in the first FORWARD run, where to my knowledge, dft sources have yet to be placed, particulaly it throws error JUST before a run ends.
