fix bug in how lumped materials were being added to mixtures
Discovered bug in how lumped materials were being searched for and added to material definitions in the case of the presence of mixtures/blends.
During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.
