Hello, I am trying to homogenize multiple universe XS using the get\_homogenized\_xs() function for various XS. I noticed that the ScatterProbabilityMatrix.get\_flux() throws an error which then breaks get\_homogenized\_xs() further down the line. Is there anyway to do a quick hotfix for this - even locally in a conda openmc installation? I attached a very simple example notebook showing this error.
