I am working in a project with four segments. I have completed roadway designer/corridor modeling/cross sections/earthwork for three of the segments. The fourth segment uses the same template, just a different alignment and tin than the other three. Everything appears to work properly until I try to run earthwork. I get an error "XS-NOPROP xs elements at station xx+xx. Therefore, results of this run will not reflect cross-section data for station xx+xx."
