I’m trying to take mgxs tallies, but I am receiving this very strange error sequence. I suspect this is failing because I am taking tallies on nuclides that exist in the materials.xml file but not in the initial materials definition. Is there a way to fix this? The code does work when the materials.xml file matches the materials definitions in the code.
