The spicepy mxvg function called here

objectsInField/oif/sso.py

Line 329 in 193b523

spicestateseq[counter]=sp.mxvg(matrix,spicestates[counter],6,6)

Had the last 2 arguments removed in the latest version https://github.com/AndrewAnnex/SpiceyPy/blob/96e8e3999c7c830e23a80b35183ddf2acb74bbda/src/spiceypy/spiceypy.py#L9157

The '6,6' probably just needs to be removed. Unknown if there are any other bugs caused by the new sp version.
