Hello Finn, I opened a bug report (https://gitlab.psi.ch/OPAL/src/-/issues/653). 

Thank you very much for reporting this. 

Would you be able to share the input files for the test you are running, maybe together with
the results of the other core. I could make a regression test out of this. 


Cheers A
