Exporting dxfs by script issue


I’ve got a long-time-used script that exports curves to DXF, I believe though a “Rhino.Command” statement. The last time I ran it I suddenly started getting a command prompt pause at the export step–for some of the exports but not all–asking me to select meshing options. I’m not exporting surfaces so I’m confused, has something changed in Rhino or should I be looking at my script?

Nevermind, looks like something about my script…
