It's been reported that a bug occurs when run_through.php reaches a (bncollege) school with multiple campuses dropdown. E.g.: http://cpcc.bncollege.com/webapp/wcs/stores/servlet/TBWizardView?catalogId=10001&storeId=65138&langId=-1
This doesn't appear to be a bug in the actual API/code, though, so not a super high priority.
