From the attached project, try to rename the simulation "Pregnant":

Application: MoBi® 12.0.340

Object reference not set to an instance of an object.

What does the "conversion of PK-Sim to Extension Module" have to do with simulation renaming?

That's a problem with the hierarchy of commands. I will fix the symptoms, but the cure might be costly.

Same exception when I try to rename the extension module "HUMAN - Maternal Structur includinge fetal placenta".
