Twiss for new SPS symmetric sequence fails

[ewaagaard]

Cloning the repo and running the test in tests/sps/test_generating_symmetric_sps_seq.py fails:

Traceback (most recent call last):

cpymad.madx.TwissFailed

Loading pre-existing sequence file SPS_2021_Pb_symmetric.seq that was generated through this method works - what happened along the way?

Also tested to go back to the commit where the symmetric case was added - Twiss still fails. Due to different version of cpymad?
