I have a design that models fine with a slab foundation, but the instant I add a subterranean foundation (crawl, finished or unfinished basement) the model fails with errors like the following:

11/7/2018 5:02 PM: 2.xml: Error: * Severe * BuildingSurface:Detailed="WALL3", invalid Outside Boundary Condition Object="UNFINISHED BASEMENT FOUNDATION 3". 11/7/2018 5:02 PM: 2.xml: Error: * Severe * BuildingSurface:Detailed="WALL6", invalid Outside Boundary Condition Object="FINISHED BASEMENT FOUNDATION 4". 11/7/2018 5:02 PM: 3.xml: Error: * Severe * BuildingSurface:Detailed="WALL3", invalid Outside Boundary Condition Object="UNFINISHED BASEMENT FOUNDATION 3". 11/7/2018 5:02 PM: 3.xml: Error: * Severe * BuildingSurface:Detailed="WALL6", invalid Outside Boundary Condition Object="FINISHED BASEMENT FOUNDATION 4". 11/7/2018 5:02 PM: 1.xml: Error: * Severe * BuildingSurface:Detailed="WALL3", invalid Outside Boundary Condition Object="UNFINISHED BASEMENT FOUNDATION 3". 11/7/2018 5:02 PM: 1.xml: Error: * Severe * BuildingSurface:Detailed="WALL6", invalid Outside Boundary Condition Object="FINISHED BASEMENT FOUNDATION 4".

Any ideas? I have attached the project file, and also shared online.
