CAD crashes and I am getting the above error while trying to edit an existing corridor. I am trying to add two different regions in an existing corridor. I accomplished this task yesterday, but due to design contraints have had to add two more regions. The two assemblies that I am using are already included in the corridor, so I know it shouldn't have anything to do with the assembly.
