Hi John, Do you know what version of OSG the model was created with?
I've noticed that older versions of OSG will crash when attempting to load osgb files created with newer versions. I haven't pinpointed exactly which version caused this issue, but it happened when I upgraded from 72 to 93. I noticed that you are using version 80, so this could explain the crashes you are experiencing.
